Hamsters are omnivores and will happily snack on a variety of fruits, vegetables, nuts, seeds, and small insects such as mealworms or crickets. Some owners do give their hamster small amounts of chicken, as an occasional treat. However, giving a lot of meat in your hamster's diet is not advisable due to the high protein content. Hamsters, however, are unlikely to scavenge and eat the carcasses of dead animals.
