Is there an animal that will overeat to the point of death?

The cassowary is a bird found in the rainforests of New Guinea and northeastern Australia. It is the third-tallest and second-heaviest living bird, after the ostrich and emu. Cassowaries are known for their aggressive behaviour and powerful kicks. They are omnivorous and their diet consists of fruits, seeds, insects, and small animals.

Cassowaries are known for their voracious appetite and will often eat until they are sick or even dead. In one case, a cassowary was found dead with its stomach so full of food that it had burst. This is a rare occurrence, however, and most cassowaries are able to regulate their food intake.
