 Item No. SCP-581 Object Class Safe Special Containment Procedures Except for approved testing, SCP-581 would be kept at minimum 1000 meters from all members of all equine species. SCP-581 would be kept in locked climate control facilities. No firearms are allowed in proximity to any examples of SCP-581-2. Description SCP-581 is a horse's nose bag made from leather. In any equine subject, horses, mules, and donkeys have all been confirmed to be susceptible. Zebras, onagers, and other non-domesticated hybrids have not been tested due to budgetary reasons. Within 500 meters is potentially an instance of SCP-581-1. SCP-581-1's sole motivation appears to be inserting its muzzle within SCP-581. This is strong enough to override instinctual reactions to predator urine or females in heat, and has caused instances of SCP-581-1 to harm themselves in the process of attempting to free SCP-581 from within steel safes. Only one instance of SCP-581-1 is known to exist at any time. Examples of SCP-581-1 will actively resist being removed from SCP-581's range of effect and will sicken and 90% die within a week of SCP-581 being forcibly removed. If SCP-581-1 succeeds in inserting its muzzle within SCP-581, it will become an example of SCP-581-2. SCP-581-2 is an equine characterized by several anomalous behaviors. These behaviors seem to indicate that SCP-581-2 believes itself to be a human. Observed anomalous human-like behaviors include attempts to walk on its hind legs, attempts to attack its head with its front hooves, attempts to enter the driver's seat of unoccupied vehicles, fascination by and in hostility towards reflective surfaces, attempts to clasp fire arms with its front hooves, extended periods of aberrant modulated vocalizations. These are believed to be SCP-581-2's attempt to speak. Audio recordings available in archive 581-H-19. Today, all specimens of SCP-581-2 have been euthanized due to multiple limb fractures. No specimen has survived longer than two hours.
