Question
I saw in This question that cats cannot survive on a vegan diets alone, but what if the diet included common insects? Such as crickets, grass hoppers and flies?
The reason I ask is in relation to Zootopia, which explain carnivore diets as based on insect 'burgers'. relevant question here. As such I was wondering if this is a feasible solution in feline predators.
Answer
Unless insects contain significant quantities of all the essential nutrients -- specifically including taurine, which is an essential amino acid for cats since they can't synthesize it -- the answer is no. Even if you could convince the cat to put up with that diet.
Cats are obligate carnivores. Don't try to make them anything else.
