ok, he's 'not a cat that's friendly to people' yet it's allowed to be a nursing home? wtf. lol
yes, animals know that kind of thing. all the dogs my dad's had have always said their goodbyes to him before they died. they would come in to where he was, lay the head in his lap and after 5 minutes of this, walked out and fell over dead. one from an intestinal bloat, the other of 'old age.' There's a lot about the instincts of animals that's interesting to study...
