Besides mercury, there are other problems with feeding a fish-only diet to your cat. Fish used in canned pet foods are high in phosphorus and magnesium. For cats with a history of urinary tract infections or kidney disease, this can be an issue.
And while your kitty may seem "addicted" to her favorite fish, many cats actually are sensitive or even allergic to fish. In fact, fish ranks as a top food allergen (because of the high level of histamines).
Finally, tuna and other fish contain relatively large amounts of unsaturated fats. While we humans eat these fish to be healthy and decrease our consumption of saturated fats, excessive unsaturated fat may actually be harmful to cats.
To be on the safe side, feed your feline companion a well-balanced diet with variety, and try to limit fish to once a week.
