Feral

Years ago, Marc Maron trapped four feral kittens and brought them into his apartment to save them from a life on the street. At least he knew enough to keep them out of the bedroom:
When I shut the door to my bedroom to go to sleep, they’d all emerge. From under my covers, it sounded like my house was being ransacked and robbed. I would let it go on because I wanted them to have fun. When I woke up and walked into the living room there were no cats but half the couch was ripped open and the stuffing was all over the floor, books were destroyed, the rug was partially unwoven, and the TV was on.
From Maron's book Attempting Normal.
