I honestly think it wrong to force one's dietary beliefs on a pet/animal that being said my horse loves eggs ( go figure ) he also likes fish
i've never really forced my values on an animal, however my fox loved tofu..weird i know, but she loved it & i had a seagul that ony ate pasta yea i had alotta strange critters
i once had a green gecko he would go total crazy if there was any curly kale around there he could find it.. have seen him running all the way from my room to the kitchen then he sniff it in the air..
my cat absolutely loves veggie food.... like sauteed peppers are his favorite... he will eat meat though, like when i have some chicken ( i dont eat red meat ) i'll shred it up and give it to him... he likes it, but not as much as those damn peppers!
