I had a cat who was very partial to dry food. I didn’t like feeding it and tried to give him meat. He would mostly leave it and I had to give in. He liked Wilkinson’s own brand which was loose. He always had good teeth and lived until he was 21 when he had nose cancer (He was ginger and white) They are susceptible. I still wouldn’t feel happy feeding it. I am sure it was just luck that it didn’t make him ill.
