Cod

A lean white fish protein that cats accept readily and that is very low in fat, handy as a wet-food topper or appetite enticement.

1-2 small pieces of cooked fish per serving as a treat or topper; it does not replace a complete cat food.

Poach until fully cooked, debone completely and shred into strips with no seasoning; skip canned or breaded fish.

Raw cod carries parasite and bacterial risks for cats too, so cook it; salt cod is far too salty, and a fish-only diet leads to nutritional imbalance.

An easy-to-digest white fish with very low fat, useful as an occasional light extra; any bland diet during recovery from gut upset should be planned with your vet.

Cooked, 1-2 small pieces (about a tablespoon for a small dog) per serving, within about 10% of daily energy intake.

Poach or steam in plain water until fully cooked, remove every bone including fine ones, then flake it; add no salt, oil, butter or lemon.

Never feed raw cod, as raw fish may carry parasites and bacteria; salt cod, cured cod and breaded fish are far too salty and fatty, and fish alone is not nutritionally complete, so it must not be the only food long term.
