Tuna — Here’s one just for cats. Surprised? This writer was, but tuna is not only addictive for cats but can leave them woefully malnourished. If you regularly open a tin of tuna for your cat, you’re denying it the key nutrients it requires that proper cat food provides – similarly, consistent consumption of tuna can lead to mercury poisoning. Best to keep it as an occasional treat, mixed with dry cat food.
