Although it has been used for years and is found in most cat foods; fish is NOT species specific to cats who are land mammals that would never naturally jump into a body of water to catch fish to eat. They are prone to developing chronic renal failure from high Arsenic levels when fed on a fish-based diet.

This is explained by Dr Mike Davies in this very interesting podcast. Right at the end, he explains about research done at Nottingham University that found high levels of Arsenic in cats with renal disease who had been eating a fish-based diet.

These cats were compared to Scottish wildcats who had never eaten fish before and had no levels of Arsenic at all. Studies into arsenic levels found in the fur of our dogs eating fish-based diets, and the kidneys of cats fed fish food are ongoing at Nottingham University.
