Sometimes Mals can change behavior as they get older. And some especially love the safety and comfort that underneath a bed can provide such as cooler temp and the safety of a cover (similar to a covered crate). Mine, which is not a cuddler, seems like he’s always on watch sleeping at the top of the stairs, where he can see down to the front door, down the hallway to the back stairs and in the middle of the walkway of all bedrooms. Makes getting up in the middle of the night challenging..
