There is no such thing as an obnivore. An Omnivore is an animal that eats everything. They get the proper nutrition by eating a variety of plants and animals.
Two examples of obnivores are hermit crab, rats.
Hamsters are pretty robust little creatures, and very few foods afect them, although the following can cause illness:Cucumber [diarrea]Chocolate and and anything with sugar [ sickness]Unpipped fruits and vegetables [if you don't remove seeds or pips your hamster may choke]Peanut butter [ although you can give it to your rodents, I advise you to mix it with water to stop it from sticking to the insides of your hamster's food pouches]Safe treats:Shreddies with a very thin layer of peanut butter spreadCheeriosSeedless fruit and vegyogurt dropsunshelled peanuts [your hamster will have a field day trying to get the shell off and it'll strengthen it's teeth]leftover chicken, sausage or bacon [ hamsters are obnivores and surprisingly love meat! But give in small portions]Hope this helps!!!!!! Have fun with your hamster!!!
