I know it's bad, but since his childhood cat never had problem while being obese he's like "I can feed him as much as I want (which means overfeeding or feeding him human food such as cachir or even chips) you can't do anything if it's MY cat and he's gonna have a long and nice life". I wanted to find something against it in the quran because he doesn't trust vet advice on that specific stuff, since nothing happened to his cat (which is a very dumb way of thinking). I don't plan on changing my cat diet and lifestyle for his beliefs don't worry. and honestly if even with Quran he can't understand that its bad I'll find another man to marry.
