Here are reasons that dogs and cats cannot be vegan because I just want to notify everyone. ~Dogs and cats are normally meat-eating animals, they are descended from meat-eating animals. There is no reason that they could just get non-exsistant protiein. ~Normally if you think your cat/dog is vegan and you only give them biscuits, they have meat IN them. ~Dogs and cats cannot physically live without protein from meat, if you are not giving your dog or cat meat via actual meat or biscuits you're killing it and it will die. ~Humans can't survive without protein, normally you could just eat potatoes which could work because they have all of the things HUMANS need, you'd just feed your dog or cat potatoes they'd probably get sick since it's kinda just human food. ~Sure they won't get skinny but they'd get weak. ~Unless they're a furry, which can just do what it wants, they just won't live. Sorry for this but y'know I've met enough people that believe that they're not killing their animals b
