Omnivore preferably dry bones, for particular minerals and nutrients. Felines, which are usually regarded as obligate carnivores, occasionally eat grass to regurgitate indigestibles (e.g. hair, bones), aid with hemoglobin production, and as a laxative.

For example, in 2013, it was considered that American alligators ("Alligator mississippiensis") may be physiologically omnivorous once investigations had been conducted on why they occasionally eat fruits.

Miltogramminae : Members of this subfamily are kleptoparasites of solitary bees and solitary wasps. Paramacronychiinae : This subfamily includes lepidopteran predators or parasitoids ("Agria"), predators on immatures (mainly prepupae) of bumblebees ("Brachycoma") and generalist scavengers and insect predators ("Sarcophila" and "Wohlfahrtia"). Flesh flies can carry leprosy bacilli and can transmit intestinal pseudomyiasis to people who eat their larvae. Flesh flies, particularly "Wohlfahrtia magnifica", can also cause myiasis in animals, mostly to sheep, and can give them blood poisoning, or asymptomatic leprosy infections. Generally, only
