what are some vegan pets?
Large mammals: Cows, goats, sheep, llamas, alpacas, horses/ponies, & donkeys
Small mammals: Guinea pigs, rabbits, chinchillas, & degus
Birds: Pigeons & ringneck doves*** A lot of parrots are vegan, but parrots require a lot of time, research, space, and enrichment to care for properly due to their intelligence. Possible option, but research extremely carefully.
Reptiles: Tortoises - some species (like sulcata tortoises) are very long-lived & get very large, so they need a lot of special consideration for care. *** Green iguanas are vegan, but are not really recommended as a pet in general. They get very large, need enormous enclosures, and most people are NOT up for their care. Research very carefully.
Invertebrates: Millipedes, and (I think) terrestrial isopods.
Fish: I couldn’t find information on herbivorous fish other than some saltwater coral reef species. As I don’t know much about fish, I’ll leave that category for someone else to weigh in on - I don’t know if these would be species that would be highly unethical to mention as a pet (due to conservation status, ability to live in captivity, extreme care demands such as parrots/iguanas, etc.). There may be (probably are) some detritivorous fish that would be vegan, but I was having a hard time finding info on it.
(Also, of course research any pet before getting them. I just wanted to emphasize the importance of knowing what you’re possibly getting into with some of the above animals due to their extreme needs & how often they get rehomed or abandoned due to it.)
Edit: Removed snails & slugs because @beanmilks let me know they aren’t vegan! I misread the page I had read & they are more omnivorous scavengers that are primarily herbivorous (and aquatic snails are often predatory). Also removed ants because my dumb ass wasn’t thinking about that one either. Also edited isopods to be terrestrial isopods (pill bugs, sow bugs, roly polies, etc.) because there are a variety of species & the aquatic ones are often omnivorous. Still uncertain about terrestrial ones, but I’m pretty sure they are.
