We have a super king bed so lots of room for all the pets. The right side of my legs (and right at the top of the bed) have always been where the cats lie, so when the dogs move, the cats are not disturbed.

I had a hot water bottle by my feet so Dexter nicked the cats spot.
When he moved, Gizmo pinched it back.
Dexter was very sad.

I got a blanket for extra warmth for him. He still didn't look happy just lying on it so...

I wrapped it over him.
He is STILL there and currently snoring 😂
