Yep flying squirrel. I posted a thread back in 2016 about one in our closet. He’d chewed through the Sheetrock during the winter to get into our closet. I didn’t have anything worth a damn in there anyways so I let him stay, one day I forgot to close the door, and he followed me upstairs to my bedroom doorway, and I went to lay down, and he came in, and sat on windowsill next to bed watching me. I couldn’t sleep. The thought of him chewing on me while I slept. I went to go pick him up, and the damn thing actually let me pick it up. I took him back to the closet and put him a towel, some food and water in there.
