Is canned tuna good for cats, and if so, how much can they safely consume?

Canned tuna can be given to cats as an occasional treat, but it should not be a regular part of their diet. Tuna should be given in moderation due to its high levels of Mercury, which can be harmful to cats if consumed in large amounts. It is recommended to limit tuna intake to a small amount as an occasional treat, such as a teaspoon or two a few times a week. It is important to consult with a veterinarian before introducing any new foods into your cat's diet.
