I heard a Bloomberg news report on a new pet food company that is making pet food with meat substitutes Fake Meat Might Feed Your Dog and Save the Planet The dog food is vegan with the protein source made from koji which is a type of fungus. The vet who spoke in the report made it clear that dogs are omnivores and can eat a vegan diet while cats are carnivores and require meat. The vet went on to say that the company will be making a canned food for cats that is made with "fake mice". But is the "fake mice" also plant protein? So then it's not really meat. The company, Wild Earth Pets, will sell food directly to consumers. Their FB page already has negative comments.
