"Cats may scrape leaves and grass over dead prey to conceal it, and some s drag drugged but living insects into previously constructed homes so the wasp larvae can safely feed on fresh meat. But to my knowledge, only one group of animals, beetles belonging to the group ', regularly moves carcasses to a suitable place and then deliberately buries them. Unlike humans, who generally bury only our own species and those pets who have become surrogate humans, these beetles bury a great diversity of birds and mammals but never their own kind. They bury dead animals as a food source for their larvae, and the burying is a central part of their mating and reproductive strategy."
