I think dogs will do this too.
Cats? They'll sit on your corpse to interview servants to replace you.
Although it is more traumatic for whoever has to deal with the body.
> The dogs start biting and eating as a form of animal instinct. They notice you’re dead by your smell and lack of reaction, and they come and lick the unclothed areas to wake you up. If you’re dead and there’s no reaction, they switch and enter the next level—from licking to biting. That’s all. It is not a matter of hunger.
Quite sad, really.
