I could never get my cat to eat tuna, for some reason. He'd only eat Meow Mix.
Bunny-slippered Balrog. . .
My cat tells me what kind of tuna to buy: she'll only eat chunk light tuna in water. She won't touch fancy albacore, low sodium, or stuff packed in vegetable oil. And she can tell the difference between opening a can of ...say, cranberry sauce... and opening a can of tuna.
