One of the hoomans in our house has a hamster, and we want to eat it. Hoomans don't seem to understand that hamster is foods and they get upset when we try. How can we get the hoomans to let us eat that hamster?

In this case, I think it's better to ask forgiveness than permission. Just wait until they're not looking, pry the cage open, and go for it. They'll get upset, but hey you're a cat and they keep snacks as pets.
