I have been feeding both my cats raw food for years, but my female cat has started to get sick after every meal. It was suggested that I switch them to a grain free kibble. However, I know male cats need some wet food otherwise they can get crystals (happened to my cat when I was a kid).
I’d rather not feed them separate food, so how often should I give them the wet food? Is once a week okay? Or should I feed them a little wet food every day?
