If a cat or dog is eating vegan meals, they’re doing it out of their own free will, just saying. Give a dog a piece of Tofu turkey and they eat it, i didn’t force them to eat it, so.
Give a dog anti freeze and they’ll eat it. Feed a dog rat poison and they’ll eat it. Give a dog grapes, nuts, chocolate, beer, etc. They’ll eat it. They don’t know that it’s dangerous for them. As their caretaker you are responsible for knowing better, not them. If you deprive your cats or dogs of meat, especially cats, you are actively killing your companion in the slowest way.
