> Is it "inhumane" to feed cats (or other animals) the same thing every day?
Plenty of people eat the same thing every day. If your cat is fine with it and you’re fine with it I don’t see the issue. (I say this as someone who loves food, eats a variety of it, and so does my cat and did my dog.)
Are there really people that eat the same meal, breakfast/lunch/dinner, for the vast majority of their lives?
I don't think anyone would choose that, though I'm sure one could do it if the circumstances demanded it, e.g. due to poverty or being Dr. Mark Watney.
My cat ate fillet steak for dinner every night, the only complaint would be if it was not chopped fine enough and he would send it back with orders to try again.
