Can Cats Eat Sea Bass?

Yes, in small amountsTreat size for a 10 lb adult cat: About 1/4 ounce (7 grams) cooked, boneless and skinless (a few calories)

Cats can eat small amounts of plain cooked sea bass. A flake of plain white fish is a reasonable occasional treat for a cat on a complete diet. Which sea bass you buy makes some difference, because the name covers several different fish with different mercury levels. The bigger risks, as with most fish, come from bones and from the butter and seasoning that usually go with it.

What Sea Bass Offers a Cat

Sea bass is animal protein with some fish fat. It suits a cat's carnivore diet better than plant foods do, but it adds nothing that a complete cat food lacks. Mercury is the main difference between types. In FDA advice written for people, black sea bass is among the lowest-mercury fish, while Chilean sea bass sits in the middle group. The Merck Veterinary Manual notes that commercial fish products such as tuna have caused long-term mercury poisoning in cats, so a lower-mercury fish is the better habit. Merck also lists fish among the foods cats are most often allergic to.

How Much Sea Bass Can a Cat Have?

WSAVA advises keeping treats under 10% of a cat's daily calories. For a 10-pound adult cat, that is roughly 22 to 25 treat calories a day. We could not confirm a USDA calorie figure for cooked sea bass, and Chilean sea bass in particular is a rich, fatty fish, so keep the serving small. About 1/4 ounce (7 grams) of cooked, flaked fish adds only a few calories. It replaces part of the day's regular food rather than adding to it. Kittens, seniors and cats with diabetes, kidney disease, urinary stones, pancreatitis or food allergies should have the vet's approval first.

How to Serve It

Bake, steam or poach a plain piece of sea bass with no butter, oil, salt, lemon or garlic. Restaurant sea bass usually arrives with a glaze, butter sauce or crispy skin, so set aside an unseasoned piece before you cook, or skip sharing. The ASPCA lists garlic and onion among foods pets should not eat. Remove the skin, let the fish cool, and flake it while you feel for bones. Merck says bones are the most common objects lodged in a cat's esophagus. Do not offer raw sea bass or sashimi, since Merck lists raw fish diets as a cause of thiamine deficiency in cats. Fatty, buttery leftovers are worth avoiding too. Cornell Feline Health Center lists excessive dietary fat among factors associated with pancreatitis in cats.

If your cat has a medical condition or eats a special diet, check with your veterinarian before giving sea bass.

Common Questions

Can cats eat Chilean sea bass?

A cat can have a small flake of plain cooked Chilean sea bass, but black sea bass is the better pick. FDA advice for people places Chilean sea bass in its middle mercury group and black sea bass among the lowest. Chilean sea bass is also rich and fatty. Keep any serving to about 1/4 ounce, cooked plain and free of bones.

Can cats eat raw sea bass or sashimi?

Raw sea bass and sashimi are not recommended for cats. The Merck Veterinary Manual lists raw fish diets, which contain the enzyme thiaminase, as a cause of thiamine deficiency in cats. Raw fish can carry bacteria and parasites too. Sashimi also often comes with soy sauce, which is salty. Share only plain cooked fish.

Can cats eat sea bass skin?

It is best to skip sea bass skin, especially crispy restaurant skin. It holds the cooking oil, butter and salt. Cornell Feline Health Center lists excessive dietary fat among factors associated with pancreatitis in cats, and the ASPCA warns that too much salt can upset a pet's stomach. Offer a small boneless flake of the plain white flesh instead.

Can kittens eat sea bass?

A kitten can taste a small flake of plain cooked sea bass after you check with your veterinarian. Kittens need a complete growth diet, and WSAVA advises that treats stay under 10% of daily calories. Remove every bone, since bones are the objects most often stuck in a cat's esophagus according to Merck, and skip seasoned or buttered fish.

Is sea bass high in mercury for cats?

It depends on the type. In FDA advice for people, black sea bass is among the lowest-mercury fish and Chilean sea bass is in the middle group. The Merck Veterinary Manual notes that commercial fish products have caused long-term mercury poisoning in cats, with signs such as hindleg rigidity, wobbliness and tremors. Small, occasional servings of a lower-mercury fish keep exposure low.
