I heard a commercial on the radio today about vegan cat and dog food. The woman said things like how your pet sometimes might feel guilty about killing. I could not believe what I heard, the site is even weirder, they want to make vegan pet food the norm... it's vegavriend.nl (vegafriend) if you don't believe this. I'll never serve my cats vegan food, except one has a food allergy and I haven't thought of it (I only have 2 brands atm) she might not get a reaction but I know her she doesn't go for anything other than meat. But other than that, their main food will always be meat.
