You were a person Somewhat common,You were traveling around the city looking for something, but you couldn't find anything, so you explored outside the city,You found an abandoned cabin, you went inside and there was a cat there... you left, but that cat never left your head, you kept repeating it.

"There was a cat there."

You spoke but nobody believed you, you found yourself being labeled crazy, unbelievable, uh, you went back there and researched the cat... it was a being from the SCP Foundation, meanwhile, the cat showed human feet,You left but now it was repeated

"There was a feet there"

You went to the foundation looking for answers, and they turned you into a mere disposable class D, then you were sent back to the cat's place... and lo and behold, he wasn't there... but some big cat girl,She had bare feet in front of you.

"I was the cat, you silly thing."
