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.

  • Could you add some more detail? Could you describe your cat please? Apr 5 '16 at 23:41

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.

    Since I doubt anyone has actually tried it, all I can do is recommend that you look up feline nutritional requirements -- which are fairly well documented, since pet food companies use that as a starting point -- and then research which insects, if any, have significant amounts thereof. But realistically, expecting a cartoon plot device to bear any resemblance to reality is both silly and missing the point.

  • ncbi.nlm.nih.gov/pmc/articles/PMC4473169 A paper on the topic found that all but one of the insect species tested can fulfill their nutrient requirements, but still I strongly recommend sticking to foods designed for your pet, rather than messing with unknowns that could severely harm your cat if you screw up. Don't get a cat as a pet if you have moral qualms about killing animals.
