I own a cat and I have been feeding him only fish derived cat food e.g. salmon, plaice, tuna etc for over a year now. But recently he only smells his food and doesn’t eat it until very hungry. I wanted to experiment with chicken & beef cat food but they are all slaughtered in the haram way. So I wanted to know if it is not permissible to buy & feed the cat food that is haram. The cat is an indoor cat & spends most of his time on our beds and laps.

Yes you can.
