My ex husband's cat always wanted to be under blankets. If he was ever missing you could usually find him under the comforter on the bed or under a pile of my ex's laundry.
I actually had to put the laundry bag in our bedroom because Rocky would jump into it, burrow, and then fall asleep. lol I just didn't really want him being in dirty clothing, tbh. haha I just usually let him burrow in the blanket that i usually sleep with or that i lay on the couch with, and i think he likes it the most because it smells like me
Poking his head out after burrowing in the blanket. lol
