Oh wow pretty old fella! Hahah he's done with chasing squirrels now with his age. He's enjoying his retirement and is pretty demanding with his pension. :P My fat cat when she sleeps on top of my leg, she pretty much makes my leg sleep easily for how heavy she is. Maybe that's 3x more for your cat. :D
He's very cute. :DD
Lol, yeah my cat does not usually climb onto me but yeah he's heavy, 8.7 kilos if I remember correctly. When I pick up some other cat, I always wonder how light they are😅
