I have heard passing references to tuna being dangerous to cats. I thought it was because of concerns over mercury contamination (which would make it dangerous to people as well). Then I heard it also causes a deadly bladder disease in cats. Yet I think tuna is used in many canned cat foods.
I tried a search online but, as expected, I got contradictory information.
I wouldn’t feed a cat nothing but tuna, but when I open a can of tuna for a creamy noodle Mercury Helper, I nearly get wrestled to the floor by my hungry, salivating cat and end up surrendering a bite to three to him. Am I killing him?
From what i understand, tuna can be given as a treat, but a cat would not “thrive” on tuna soley, because it lacks basic nutrients cats need. Yes, tuna flavor is a base for some cat food, but catfood companies add more stuff to it for those other nutrients.
