 Item Number – SCP-247 Object Class – Euclid Special Containment Procedures – SCP-247 is kept in an enclosure of at least 20 x 40 meters, furnished based on the plans provided by the WZU, and lined with SCP-148 offset from the rest of site by at least 50 meters in order to mitigate its psychic effect. As per current containment procedures for SCP-148, its use in the containment of other SCPs is to be avoided if at all possible. 05. SCP-247 is to be fed 18 kilograms of fresh meat on a tri-weekly basis. Feeding occurs in a separate enclosure. Cleaning staff should enter the enclosure only during designated feeding times. No other access to the enclosure is allowed. The footage resulting from any violation of this order is to be archived for use in training the cleaning and monitoring staff of SCP-247. In case of a containment breach, the entire wing must be evacuated and all live footage of the incident heavily censored. The area SCP-247 occupies will be sealed off and gassed, followed by the return of SCP-247 to containment. For any reason this should become impossible, a retrieval team will be sent in armed with heavy tranquilizer rifles. Retrieval team agents must be specially selected for high reflexes, excellent marksmanship, unquestioning obedience, and low empathy scores. 05. Description. SCP-247 is a Bengal Tiger, Panthera Tigris Tigris, adult female, which to all observers appears to be a harmless cat, felus catus, juvenile female, with an orange and black striped coat resembling that of a tiger. Remote feeds and still photos also show this illusion, although it is unknown whether the photo itself is affected, or merely the observer. SCP-247's true nature has been confirmed by analysis of weight, water displacement, and dental molds made from bite marks. It is unknown exactly how SCP-247 generates this illusion. There are two components to the illusion. First, a memetic effect that changes the perceived image of SCP-247 to that of a kitten. And second, a psychic component which radiates outward from the subject, diminishing according to the inverse square law, and reaching half-strength at f***ing meters. Any sentient being within this field comes under the impression that SCP-247 is completely harmless, regardless of prior knowledge or experience. Individuals in this field also show extreme reluctance to harm or allow others to harm SCP-247, even while being actively harmed by the subject. This psychic field can be blocked with SCP-148, or avoided by striking from well outside its effective range. The memetic effect is not blocked by SCP-148. As of yet, no one has been able to see SCP-247 as anything but a small striped cat. Typically, SCP-247 will begin to purr or mew when approached by a human. The human will remark that this is adorable, an approach to pet the subject. This has been observed even in persons who strongly dislike cats. SCP-247 has been known to accept affection from its victims for upwards of 7 minutes before disemboweling and devouring them. Genetic analysis shows slight deviation from a typical Bengal Tiger's genotype, indicating possible contamination data expunged. All further breeding experiments require 05 level approval. The resulting hybrids have been designated SCP-247-1. Addendum 247-A, a series of tests in exposing SCP-247 and the control subjects to various non-human animals. Control testing took place in an exact replica of SCP-247's enclosure. Control-A is a yellow kitten, matching SCP-247's apparent size and age. Control-B is a fully grown Bengal Tiger, matching SCP-247's actual weight. Control-Log 247-A-1, date, 2010. Test subject, a mixed breed dog, mostly terrier, a known cat chaser. Control-Test-A, subject immediately began barking and ran of the control, which retreated up a nearby tree. Control-Test-B, subject cowered in the corner as far from the control as possible. Control took no notice of subject. Results. Subject ran toward SCP-247, barking loudly. At approximately 5 meters away, subject slowed to a halt and became silent. At this point, SCP-247 rolled over and made a mewing sound believed to be a sign of annoyance. The subject retreated to a far corner of the enclosure, with its tail between its legs. Notes. That was extremely odd. Further testing recommended. Researcher S. Approved, 05- experiment log, 247-A-02-I-I-I, date, 2010. Test subject, a male tabby kitten with the same apparent age as SCP-247. Control-Test-A, subject played with the control in the manner expected of kittens. Control-Test-B, subject climbed a tree and attempted to hide itself from the control, displaying visible signs of terror. Results. Test 1. Subject approached SCP-247 and mewed. SCP-247 responded in kind and played with the tabby kitten. The resulting footage is extremely odd. At one point, SCP-247 lifts the subject, which appears to be the same size as SCP-247, with a single forepaw. While at another point, SCP-247 lifts the subject with its mouth, clearly showing that its mouth is much larger than it appears to be. The leading researcher characterized this as adorable, but remarked that it gave him a headache. Due to a faulty recorder, this test had to be repeated. Results. Test 2. Subject approached SCP-247 as above. SCP-247 made a deep purring sound, analogous to a growl. Subject reacted as in Control-Test-B. Notes. This seems to indicate 247 has some degree of conscious control over its apparent appearance. Researcher S. Experiment Log, 247-A, 3. Date. 2010. Test Subject. An adult male deer, a normal prey animal for a Bengal tiger. Control-B and SCP-247 were not fed for three days prior to this experiment. Control-Test-A. Subject grazed. Control fell asleep two minutes into the experiment. Control-Test-B. Control attacked, killed and devoured Subject, which behaved normally for a deer trapped in an enclosed space with a large predator. Results. Subject began grazing as in Control-Test-A. SCP-247 approached it calmly and killed it with a single bite to the neck, then proceeded to devour the subject. Test was repeated without SCP-247 being forced to fast. SCP-247 completely ignored the subject for over a day, before apparently becoming hungry and killing it, again with a single bite to the neck. Notes. SCP-247 seems to prefer humans, both as food and for entertainment. Other prey animals presented to SCP-247 were all killed in a single strike, while humans are invariably allowed to pet the SCP for some time before being killed, and are sometimes mauled and played with the way a cat will play with a mouse. Furthermore, the SCP has killed every human it has had the opportunity to kill, regardless of hunger. Researcher S. Experiment log 247-A-8. Date. 2010. Test subject. An adult female chimpanzee. Control-Test-A. Subject and control ignored one another. Control-Test-B. Subject retreated to a tree, showing some signs of unease. Control displayed some curiosity towards the subject, but did not attack. Results. Subject approached SCP-247, made noises identified as signs of affection, and began to groom SCP-247. SCP-247 allowed the subject to groom it for over an hour, then messily killed and devoured it. Notes. This seems to be its typical reaction to unfamiliar prey animals. It seems to prefer to prey on apes with advanced social behavior. Experiments with gorillas and other social apes have shown similar results. Essentially, SCP-247 is a large predator that has somehow adapted to take advantage of the largest available food source. Humans. We should investigate all future reports of man-eating tigers, in case there are more of these things. Researcher S. Experiment log 247-A-12. Date. 2010. Test subject. An adult female grizzly bear. Control-Test-A. Control fled up a tree in terror. Subject ignored it. Control-Test-B. Subject and control acted nervously and gave one another as large a birth as possible. Results. Initially, subject and SCP-247 ignored one another. At one point, subject came very close to SCP-247, resulting in SCP-247 giving a warning growl. Subject responded with hostility. Suborted due to possible harm to SCP-247. Subject tranquilized by Foundation personnel and subsequently killed by SCP-247. Notes. Future tests involving animals potentially capable of killing or injuring a Bengal tiger are cancelled. Researcher S. Experiment log 247-A-13. Date. 2010. Test subject. An adult female Bengal tiger. Control-Test-A. Control fled up a tree in terror. Subject ignored it. Control-Test-B. Subject and control greeted one another, established the order of social dominance, then both fell asleep. Results. Identical to Control-Test-B. Notes. Interestingly, SCP-247 was the beta animal in this interaction. Researcher S. Experiment log 247-A-14. Date. 2010. Test subject. An adult male Bengal tiger. Control-Test-A. Control fled up a tree in terror. Subject ignored it. Control-Test-B. Omitted. Record of normal Bengal tiger mating behavior substituted. Results. As expected based on control-B. Data expunged. Notes. Researcher S. has been removed from this project for lax security in his experiments, although in light of his injuries, further disciplinary measures have been deemed unnecessary. Data expunged, which seems to have benefited from a form of hybrid vigor, has been designated SCP-247-1. Considering that SCP-247 is likely to have bred naturally in the wild, Mobile Task Force Iota 5 Tiger bait has been formed and assigned to hunt down and contain or destroy all incidences of the hybrid SCP-247-1. Item number SCP-331. Object Class. Safe. Special Containment Procedures. When not being used, SCP-331 is to be kept within a typical electronic seven-digit metal safe and Dr. Williams' office. The code is to be changed on a monthly basis by said doctor. People who wish to examine SCP-331 must ask for authorization beforehand. As of date undisclosed, SCP-331 is worn by SCP-331-1. Description. SCP-331 is a red plastic cat collar, approximately 23 cm in length. Metal studs surround the collar in intervals of 1 cm. Testing has confirmed the metal to be nickel. The bell consists of stainless steel, electroplated with 24-karat gold. Ringing the bell has no distinguishable effect, adverse or otherwise. The word Tumbles has been painted on the back of the collar in yellow paint. Testing has confirmed that there is nothing unusual about the paint. SCP-331 exhibits no abnormal tendencies when worn by a living cat. When SCP-331 is fastened around the neck of a deceased cat, hereafter SCP-331-1, SCP-331-1 is resurrected, with no initial adverse effects. The collar does not halt the decomposition process, however. Fur and skin still rot at a regular pace. Organs are unaffected by the decomposition process. Testing has yet to determine the exact cause for this. SCP-331-1 shows no signs of distress during the decomposition process. SCP-331-1 can be killed by conventional methods, whereupon it remains deceased. The separation of SCP-331 and SCP-331-1 data expunged. Unless SCP-331-1 is deceased, it should be noted that SCP-331-1 always answers to tumbles and has an amiable personality, despite what it was called or how it behaved pre-mortem. SCP-331 was discovered when reports reached a Foundation agent of a zombie cat, witnessed around B***** Park. Said agent immediately alerted the Foundation of a possible outbreak of SCP-8. MTF B***** was dispatched and neutralized SCP-331-1, whereupon it was transported to Site B***** after no trace of SCP-8 was detected. Upon arrival, research was conducted on SCP-331 that confirmed its properties. Item Number SCP-511 Object Class Euclid Special Containment Procedures When an instance of SCP-511 is identified, the affected residents shall be quarantined and will receive the next sequential Site designation. Accepting one main entrance, sites hosting SCP-511 will have all points of possible entry or exit permanently sealed with appropriate building materials. The main entrance will remain locked at all times. Entry is permitted to Foundation personnel with written authorization from level 3 or higher. All SCP-511 sites will be equipped with remote monitoring equipment, allowing for 24 hour surveillance and a continual tracking of the numbers of SCP-511-1 inhabiting the site. At all times, one Class D personnel will be resident in the site. Personnel with this assignment are exempted from monthly termination for the duration of assignment. Candidates for this assignment shall be exclusively drawn from a population of post-menopausal women with a global clinical dementia rating of 2 or greater. Note Due to the exclusive nature of this population, 05-1 has approved recruiting from local hospice and or nursing homes if necessary. The population of SCP-511-1 within a site must remain within an optimal range of 50-1 individuals. Below this range, adult felus domesticus should be introduced to the site to increase population to minimum levels. If population exceeds red individuals, it must be culled immediately. Any SCP-511-1 found outside the containment site shall be euthanized, and the remains incinerated. Any biological material leaving the containment site for testing will be handled in accordance with standard protocols for a level 4 biohazard. All specimens are incinerated after testing is complete. Before coming in contact with any material from the containment site, personnel must be inoculated for influenza, hepatitis A, hepatitis B, tetanus, tick-borne, and encephalitis. Full medical work-ups are mandatory on a bi-weekly basis for personnel working with SCP-511. Description Instances of SCP-511 typically occur within residential structures with a block or stone foundation that includes a basement or crawl space. All attempts to remove an instance of SCP-511 from such a residence have proved ineffective. SCP-511 is always found associated with a colony of feral felus domesticus, common domestic cats. Members of this colony are designated SCP-511-1. SCP-511 is a mass of biological matter, taking the form of a large feline, often with extra limbs, eyes, mouths, or other organs. It is typically coated with dirt, blood, and fecal matter, making its fur appear black despite its actual coloring. Tests have shown SCP-511's fur to actually be a random patchwork of various feline coat patterns, colors, and lengths. SCP-511's mass varies from 10 kilograms to over 50 kilograms, roughly in proportion to the number of SCP-511-1 in the associated colony. The tissue that makes up this mass consists primarily of the bodies of deceased SCP-511-1. The portion of SCP-511 that does not comprise SCP-511-1 consists of other biomass, small rodents, various plant materials, insects and insect larvae, black mold, a human data expunged. Incorporation of dead tissue into SCP-511 does not appear to slow the normal process of decay. Different areas of SCP-511 undergo different stages of biodegradation at any given time. Some areas show little more than levidity, while other areas may show active carrion insect infestation, and some areas may even show liquefaction of tissues. Note, researchers have described SCP-511 making a purring sound. Tests have shown this sound does not originate with SCP-511, but is actually the sound of insects, most often blow flies, trapped within its mass. Dr. A. SCP-511 prefers to inhabit dark spaces with a relatively high humidity, such as old basements and crawl spaces. It will continually scavenge its immediate area for new biomass to incorporate into itself, displacing an expelling matter that has decayed past mechanical usefulness. Examples of SCP-511-1 resemble ordinary felus domesticus that have undergone extreme neglect. They display a body condition score of 2 or 1, regardless of the amount of food available. Ulcerated skin is common, as are parasitic infestations, tumors, and various viral and bacterial infections. SCP-511-1 are known carriers of a particularly virulent strain of- A typical SCP-511-1 shows no interest in grooming itself, and as patchy and matted fur. It is unclear to what extent the physical condition of an SCP-511-1 is a result of the influence of SCP-511, and to what extent it is due to suboptimal living conditions. Several observations have been made of an SCP-511-1 retrieving biomass from elsewhere, and bringing it to SCP-511 to be incorporated. Addendum 1. Incident Report of Containment Breach at Site-511- Incident I-511-11 Personnel Involved D-78-56 Male Subject 35 Years of Age Date 08-27-19- Location Site-511 California Description After determining that a permanent human presence at an SCP-511 site results in moderation of aggression in SCP-511-1, containment protocol is updated to require Class D personnel reside on site. In the event the original homeowner is deceased. Six months after this policy is established, D-78-56 is assigned to Site-511. As expected, within a week, aggression levels of SCP-511-1 toward Foundation personnel lessened considerably. 16 days after being assigned to Site-511, D-78-56 begins showing signs of increased aggression. Only abusing Foundation personnel and engaging in superficial vandalism of Site-511, D-78-56 is reprimanded. 18 days into his assignment, D-78-56 interferes with the Foundation team by throwing garbage and yelling obscenities. D-78-56 is subdued with a tranquilizer dart and locked in his quarters. At 20 days, D-78-56 begins capturing SCP-511-1 and data expunged is only discovered when a Foundation research team enters for routine specimen collection 48 hours later. The team discovers remains from 37 separate SCP-511-1 collected in the kitchen. Bodies are dismembered and show signs of data expunged. D-78-56's body is discovered in the basement after an apparent attempt to data expunged. Site-511 is incinerated as an emergency containment procedure. Okay, I think there's something to the crazy cat lady idea. Think we need to be more careful with the class D's on this one. Dr. A. Addendum 2. Interview with Agent R. Survivor of containment breach at Site-511-47. Interview 511-A. Interviewed. Agent R. Interviewer. Dr. A. Forward. Agent R was sole survivor from Mobile Task Force assigned to retrieve an SCP-511 for study from Site-511-47 after the death of the homeowner, Mrs. B. Interview takes place at St. B. Hospital in B. Ohio. Begin log, 11-05-13-30. Dr. A, how are you feeling? Agent R. Ugh. Like I've had half my face ripped off. How do you think I feel? Dr. A, I want to talk about the containment breach. Agent R. Unintelligible. Dr. A, we have some questions. Agent R. Of course you do. Dr. A, starting with, why was there foreign matter introduced into the containment unit? Agent R, do you have any idea what we were dealing with? Dr. A, why don't you tell me? Agent R. We were tasked to retrieve a 40 kilo thing with a BSL-4 containment unit. You know how big those units are. Dr. A, I know the specifications. Agent R. Like lugging a self-propelled washing machine. Now, imagine dragging one of those into one of these places. You already got reduced mobility from the hazmat suit, got 50 kilos of gear, and you're walking into a house that has two or three decades worth of garbage in it. We have cat ankle deep in places, trash bags split open, piles of soggy newspaper and junk mail, boxes of clothes, furniture that looked like it exploded, and cats everywhere, eyes everywhere. Dr. A, can we return to the containment unit? Agent R. We have chest high in places, cats everywhere, and space is so tight that we have to go single file. No way a guy in full gear can turn around and forget the containment unit. Just one look and there's no way we can use data expunged. Dr. A, so it was Agent R's idea. Agent R, and it was that or pack it in, can't get downstairs, so we bait the unit with the body and point it at the basement door. According to the briefing, it would be attracted to freshly dead biological matter. Dr. A, and SCP-511 was attracted to the baited unit. Agent R, the most nerve wracking 20 minutes of my life, listening to that thing pull itself upstairs, thud, thud, thud, and those cats watching us. You know how freaky cat eyes look with night vision equipment? Dr. A, so you captured SCP-511. Agent R. Dr. A, what happened then? Agent R, we got out as quickly as we could. No one can turn around so we back out, all those eyes watching us, staring. Dr. A, you were first out the door. Agent R, last in, first out. We all got out for all the good it did. We thought we'd pulled it off, but the moment the containment unit rolled out the door, it they... Dr. A, what happened? Agent R, you ever see films of explosive decompression? That's what happened to it. Splattered itself all over the insides of the containment unit. And those cats, those f***ing awful cats, they howled. Then they rushed us. Dr. A, did you attempt to contain the breach? Agent R, you're kidding, right? Two or three hundred of them. Not just the door, but the windows dropping on us from the second floor. When I saw r*** disappear under them, I just ran and locked myself in the van. I'm not proud of that. Dr. A, I'm not here to judge. I'm here to determine what happened, so it does not happen again. Agent R, well, you see what happened to me? That was one of them that got locked in with me. One, if you don't reclassify these things, keter, you're insane. Dr. A, I will be recommending updates to containment procedure. Agent R, yeah, while you're updating things, there's something else you need to update. Dr. A, what's that? Agent R, the briefing was all about how SCP-511 is influencing these cats. That's wrong. Dr. A, how so? Agent R, SCP-511 doesn't influence anything. It's the cats. They made SCP-511, and they made it because they hate us. End log. Closing statement. Agent R died three days later from complications due to blood poisoning. Three weeks after containment breach, a new incidence of SCP-511 was identified in... Ohio, 35 kilometers southeast of site 511-47. Remote biopsies of this new incidence reveal genetic material identified is coming from three agents of Mobile Task Force. It seems that the destruction of SCP-511 might only displace it elsewhere. Until we better understand the vectors that propagate it, all SCP-511 need to be contained in place. Request for reclassification of SCP-511 to keter is denied. O5... Item number, SCP-529. Object class, safe. No containment procedures. No special precautions have yet proven necessary. Josie is quite affectionate, and at this stage is free to move about the lower levels of the facility. Staff are not permitted to feed cheese to her. She will become distressed if not given sufficient cheese. Description. SCP-529 is a small house cat, Phyllis Catus, with gray tabby markings. Most of the animal to the rear of the end of the rib cage appear to be missing. The body terminates sharply, as if sliced in two. In spite of this, the animal has no health problems, and moves about as if its hindquarters were still in place. For example, walking takes place as usual, and sometime after feeding the animal makes motions, as if to avoid itself of waste matter. The cross section does not display the interior of the animal, but appears pure black to the eye, and absorbs all non-visible wavelengths of light. It is slightly yielding to the touch. Gentle stroking of this area sometimes yields a positive reaction, purring and so on, but more usually leads to the creature turning on the agent, claws at the ready. Those scratched have experienced no abnormalities. Hind regions do not appear to be invisible. A cursory examination will show that there are no hindquarters. DNA testing has shown the animal to be female.
