My son had a snow day and inadvertently our tabby got locked in the spare bedroom. He was in there about 12 hours. My kid was upstairs all day and never even noticed only 2 cats were hanging with him. I got home after 6 tonight and noticed the tabby didn't greet me as usual. I called him and the tuxedo led me to the spare room. When I opened the door, the tabby ran out and the two were excitedly licking each other's heads. She must have been hanging out all day on the other side of the door. It was the sweetest.
