SCP-XXXX; Item number:; Euclid; SCP-XXXX is to be held in a 10 meter by 10 meter by 10 meter cell with heavily armed guards inside and outside at all times. If SCP-XXXX enters a state of hostility, all personnel are to evacuate the cell until it has returned to a state of passiveness. SCP-XXXX appears to be a tabby cat that acts friendly to all creatures, with the exception of humans under the age of ten years old. If the anomaly is left without a human in a ten meter vicinity for one hour or longer, it will begin to frantically pace the cell, unless it is larger than ten meters. If any creature attempts to touch SCP-XXXX, the anomaly will become hostile to all creatures for approximately ten hours. During a state of hostility, personnel of only level 4 and higher may enter the cell. In the event of a containment breach, the cell is to be locked down, under the same conditions as a state of hostility.
