Just searched the house and garage for one of my 3 cats when I realized I hadn’t seen him in quite awhile and that in that while I’d had the outside garage door open. I was nervous. I looked everywhere and finally found him crammed under a small 3 shelf TV stand. He wasn’t scared, he’s got a full belly, purred when I pulled him out. Why crawl into that tiny little space? To see if he could fit.
Our oldest cat who passed last year (tall Russian Blue) destroyed many a shoebox slightly smaller than his body just so he could fit.
Do your cats and dogs like to fit spaces just to fit? It’s like a kid w/ a new box.
