Hi ninathenana, generally wet cat food isn't a complete food.
Bozita (no, no shares in the company), is a complete food without cereal. Cat's shouldn't eat cereal. If a roaming cat eats a mouse at a time, it/they will only contain 1% cereal. It took hours of online research before I found Bozita. So good luck.
Pet food companies bulk their food by adding cereals and other c##p, which shouldn't form part of their diet. Was about to type that cats don't eat veg, yet, a previous cat of ours, used to nibble the tips of carrots
.
There have been a few cases when cats had allergic reactions to cereal when added to kibble. Those reactions meant a trip to a vet.
