Sometimes Friend will share “her" spot with Max. Old cats will train up a new pup with surprising quickness. Owl
One of my late cats used to get in that twisted position in front of the insert. I nicknamed him pretzel puss. Sometimes I'd come home from work after a cold day and crash on the floor in front of the insert. He'd come over and crash with me.
No pictures, but our twenty something year old will sit within inches of the front of the IS. Amazing how hot he would get when sitting like that. Must feel good on his old bones.
