Item #: SCP-5196
Object Class: Euclid
Special Containment Procedures: SCP-5196 is to be contained in a chamber with access to a sustained supply of cat food (not Meow Mix), at 101.5 °F, or 38.6 °C.
Description: SCP-5196 is a felis catus1 with facial features closely resembling that of a human, but disproportionate. It's lips are twice the size of it's eyes, and it's nose is similar in size to that of a grape tomato. It weighs approximately 16.8 lbs (about 7.62 kg), and is 16 inches in length (40.64 cm).
If SCP-5196 is supplied with Meow Mix cat food, it will involuntarily exert acid from its 50 acid pores, the speed of which is about 48 mph. If SCP-5196 has not consumed for 72 hours2, it will hiss at approximately 150 decibels3, and claw viciously at the containment chamber walls. Afterwards, it will reverse-age into a kitten, and repeat the aging process for about 68 hours. After 68 hours it will stop aging. When SCP-5196 is in its shrunken form, it weighs about 15 ounces.
Addendum 5196-1:
Event 5/4/20██
Excerpt from Dr. ██████'s letter to Dr. █████
SCP-5196 was found inside an apartment room next to a deceased woman. The woman, by the name of █████ ████, had a hydrofluoric acid-resembling burn across her torso. Based on our recent studies conducted on the specimen, I've concluded that SCP-5196 had consumed the Meow Mix from the cat bowl (labeled Kitty), and had screeched loud enough to rupture the poor woman's eardrum, which is most likely the cause of her bloody ears. The reasons for Meow Mix causing this reaction is because of the ingredients in the food. These ingredients can trigger the defense mechanism of SCP-5196.
Addendum 5196-2:
Interview with █████ ████'s neighbor

SPEAKER: How are you doing today?
SPEAKER 2: With this warm weather, I'd say pretty well.
SPEAKER 1: I'm here to ask you about what you know from yesterday's incident. To begin, where were you on May 4?
SPEAKER 2: I was in my apartment, watching TV. My kids were hanging out with their friends, so I had nothing better to do. That's when I heard screaming. I hadn't slept since the night before because I was binge-watching The Office in my room, so when I heard the screaming, I just thought I was imagining things. That's usually what I do whenever I haven't slept.

SPEAKER 1: Right… next question. Did you know the victim personally?
SPEAKER 2: No, not really. I just knew her as the Karen who yelled at the people playing loud music in their rooms, as it "disturbs her creative thinking." That was her catchphrase. Poor gal couldn't catch a break [laughs].
SPEAKER 1: And did you see any of what had happened?
SPEAKER 2: Only from the news. I'm telling ya, it was everywhere! Everytime I switched channels, there was "Woman dies from suspicious acid burns, culprit not found" and "███████ woman dies from self-inflicted acid burns." I can't escape it, man.
SPEAKER 1: Alrighty then. Thank you for taking your time to stop by. Have a good rest of your day.
