Why not make pet food out of bugs? My cat already enjoys eating bugs and bugs are a good source of nutrients. I'd never eat bugs knowingly and yes I do understand that it is a notion based on my association between bugs and uncleanliness and that's true but I don't care. My point is my cat is already down to eat bugs but nobody is offering highly nutritious cat food made with bugs. Why not start with things easier to change?

Because it's not about the environment. It was never about the environment.
