My Cat Coco... she is a bit of a special type 🤣. I've never had a cat that actively wants to sleep under duvets. She looks for gaps where she can slide in, and then curls up in the crook of my legs (I side sleep!). She must be absolutely boiling under there... I thought she might stop in summer, but nope!
Anyone else's cat have this weird habit?! I did have one cat once who was even weirder. She actively sought out cold spots to sleep in. Including (but not limited to): marble fire surround, drafty windows, bag of frozen food, in front of fans...
Cats never cease to amaze me with their weirdness!
