Cats can eat tuna in water, but only as an occasional treat. It is safest to offer tuna that is chunk light, packed in water, and free of added preservatives, salt, or seasonings. Tuna water from such cans is also safe in small amounts. However, tuna should not be a regular part of a cat's diet due to risks such as mercury toxicity, nutritional imbalances, and potential allergies. Feeding tuna too often, or albacore (white) tuna, which has higher mercury levels, can be harmful. The recommendation is to feed tuna treats like 1 or 2 teaspoons once or twice a week at most, with the majority of the cat's diet being balanced cat-specific food. Also, kittens under one year old should generally avoid tuna. In summary:
- Feed only chunk light tuna in water, no additives.
- Tuna water is safe as an occasional treat.
- Avoid tuna in oil, albacore tuna, and seasoned tuna.
- Limit to an occasional small portion, about once a month for treats or up to once/twice a week in very small amounts.
- Do not feed daily or large amounts to prevent health issues such as mercury poisoning or vitamin deficiencies.
- Always consult a veterinarian when changing diet or introducing new foods.
This ensures cats benefit from the occasional tuna treat without risking their health.
