 Item Number – SCP-581 Object Class – Safe Special Containment Procedures Except for approved testing, SCP-581 must be kept a minimum of 1,000 meters from all members of all equine species. SCP-581 is to be kept in locked, climate-controlled 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. Any equine subjects, 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. 1,500 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. SCP-581 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 then hostility towards, reflective surfaces Attempts to clasp firearms with its front hooves Extended periods of aberrant modulated vocalizations These are believed to be SCP-581-2's attempts to speak Data expunged To date, all specimens of SCP-581-2 have been euthanized due to multiple limb fractures. No specimen has survived longer than two hours. Lesson complete. If you missed the previous orientation, go watch SCP-580, Shi Hong-Ti's Five Heaven Chariot, right now.
