Can Cats Eat Tuna?
Tuna is high in protein and contains omega-3 fatty acids, which can support your catโs skin and coat health. Many cats love the smell and taste of tuna, making it a popular choice for treats.
Cats can safely eat:
- Plain, cooked tuna
- Canned tuna in water (low sodium)
- Occasional treats made with tuna
โ ๏ธ When Tuna Can Be a Problem
Too much tunaโor the wrong typeโcan lead to issues:
- Mercury exposure: Tuna, especially large species like albacore, can contain mercury. Frequent feeding increases the risk of mercury poisoning.
- Nutritional imbalance: Tuna lacks essential nutrients cats need, like taurine and vitamin E, so it shouldn’t replace a balanced cat diet.
- Addiction to tuna: Some cats may become picky and refuse other foods if given tuna too often.
- Tuna in oil or brine: These versions are too fatty or salty and can upset your catโs stomach or strain the kidneys.

Why Your Cat Will Love These Treats
Cats are naturally drawn to the strong aroma and taste of tuna, making it an irresistible ingredient. Tuna is rich in protein and omega-3 fatty acids, which help support a healthy coat, skin, and joints. Paired with egg white, which adds more lean protein and helps bind the treats, this recipe is both tasty and nutritious for your cat.
Ingredients
Just 3 ingredients make these tasty cat treats.

Tuna in Water
Tuna is the star of this recipe and a favorite among cats for its strong scent and rich flavor. Using tuna packed in water is importantโit’s lighter and safer for your cat compared to tuna in oil or brine. Tuna is high in lean protein and omega-3 fatty acids, which support skin, coat, and joint health. Choose low-sodium or no-salt-added varieties for optimal safety.
Egg White
Egg white acts as a natural binder in this recipe, helping the treats hold their shape when baked. It also adds a boost of high-quality protein with virtually no fat. Egg whites are gentle on your catโs stomach and a great way to create a light, fluffy texture in baked treats.
Dried Catnip (Optional)
Catnip is a fun, aromatic herb that many cats go wild for. While it doesnโt offer nutritional value, it does provide sensory enrichment and can make treats more exciting. Not all cats respond to catnip, but for those that do, it adds an extra level of enjoyment. Be sure to use pure, food-grade catnip without additives or artificial flavors.
