Mazryonh said: Don't you mean "Kotatsu Neko"? It's a small claymation series about a cat who won't leave a kotatsu under any circumstances, viewable here:
In some slavic languages (like russian or polish) 'kot' means 'cat', which sounds hilarious, because it's kot-atsu, with a 'kot' under it, and 'atsu' means hot in japanese, you know, a kot is atsu and he's under kotatsu... yeah :D
