Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be kept in a 4 meter by 5 meter room with the amenities of a normal house cat. This includes one cat tree, one full size plush cat, one litter box filled with clay clumping cat litter, one bowl to be filled with food twice a day, and one bowl to be filled with water. SCP-XXXX’s water and food bowl is to be refilled as needed by D-Class personnel.

Description: SCP-XXXX appears to be an ordinary Felis catus, of the Persian breed, with black fur and orange eyes. SCP-XXXX weighs eleven pounds and has a very friendly attitude towards researchers and D-Class personnel. SCP-XXXX’s anomalous properties manifest when a human being enters the same room as it. Upon entering the room, the person will begin to hear the thoughts of SCP-XXXX through auditory hallucinations, these auditory hallucinations can also be picked up by recording devices. SCP-XXXX has given itself the name “Chester” and will only respond to researchers and D-Class personnel when it is addressed as such.

Upon entering SCP-XXXX’s containment cell, personnel will be greeted by SCP-XXXX and it will begin to attempt to converse with the subject (See interview XXXX-1). If personnel mention that they previously owned a pet cat at any point during the conversation, SCP-XXXX will then render the person unconscious through unknown means.

After approximately four to seven minutes after becoming unconscious, a ghost-like instance of SCP-XXXX-A will appear out of the subjects mouth. SCP-XXXX-A is an incorporeal entity, that becomes tangible when played with or pet, resembling that of a Felis catus, and upon its manifestation subjects will awaken. While each entities appearance differs, all entities share the same orange eye color, and all subjects claim they had a cat that resembles the instance of SCP-XXXX-A (See test log XXXX-α).

SCP-XXXX-A will exist as long as the subject pleases and is friendly towards researchers and staff. Friendly behavior includes purring, curling up next to or on subjects, and playing with toys that it manifests. SCP-XXXX-A will dissipate whenever the subject tells it to “go away” or after thirty two (32) hours and eight (8) minutes of neglect. SCP-XXXX appears to deem neglect as ignoring SCP-XXXX-A, not petting it within the thirty two (32) hours and eight (8) minute time span, or not playing with SCP-XXXX-A within the time span.

Addendum XXXX-1: It appears as though SCP-XXXX is unwilling to answer any questions about its origins or abilities. Any mention of it’s past is met with loss of cooperation and silence. It also seems that SCP-XXXX reacts violently to anyone who has abused animals in the past. SCP-XXXX is pending Euclid status upgrade in light of incident XXXX-1

Incident XXXX-1: Entity is extremely hostile towards D-1736, and appears invulnerable to conventional weaponry, killing █ security staff in order to get to D-1736. Upon reaching D-1736, the entity begins to claw at D-1736 while repeating the phrase “Destroy the black heart. Cleanse the evil.” D-1736 eventually expired due to extensive lacerations. Entity remains in the area for an additional eight (8) minutes muttering the word “Cleanse” while patrolling the area around D-1736. After the entity vanishes, an autopsy is performed on D-1736. It was discovered that D-1736’s heart had been removed and its location is currently unknown. SCP-XXXX is now pending Euclid status.
