Well, not exactly cuddles (or cuddles at all), but eating rabbit can certainly be the death of you.

Rabbit starvation - or the more exotic name mal de caribou - shows up when you eat too much lean meat and are, you know, trapped in a desert or the tundra or a similarly punishing environment. Your kidneys can't handle the high amounts of protein without supplemental fat/carbohydrates and you'll soon be pushing up daisies. It works the same way for anything that's lean - caribou and other game meats are primary examples.

in 1881, Adolphus Greely went sailing around the Arctic at the request of the US government in an attempt to collect some meteorological data and readings on the magnetic poles. Turns out he wasn't very good at it, though, and him and his crew ended up stranded until rescued in 1884. Only 6 of the 25-man expedition survived. Lacking proper rations, I daresay a few of the dead found their bodies a bit snacked-upon, too.

Vilhjalmur Stefansson, an Artic explorer with a super cool name, attributes some of their deaths to rabbit starvation as a result of eating too much lean human flesh. Sounds like a pretty good post-mortem revenge scheme on the corpse's part.

Added bonus: here's a really long list of euphemisms for death. Examining the radishes has potential, I think.
