I work in a vet clinic and we see people trying to force their cats/dogs to be 'vegan' all the time. When you explain that cats can't survive without meat, the argument is usually that "soy protein fills the same role as meat protein"...umm, yeah cause beans have all the same vitamins and amino acids as animal muscle and organs...People are just...ugh. This is why I like animals :/
While on the subject, the vegans I know also are firm believers that it is cruel to keep any animal in a cage. So I really should just let the snake and fish roam freely all over the house. If they truly love me, they won't run away, right?
