Sometimes — with care
Cooked, plain, boneless salmon is a safe occasional treat that most cats adore — but it shouldn’t replace a balanced cat food, and raw salmon is a no.
Cats are obligate carnivores, so a little cooked salmon is a biologically appropriate, protein-rich treat with omega-3s that support skin and coat. The cautions: it is incomplete nutrition (a salmon-only diet lacks taurine balance and other nutrients), so it must stay a treat; raw salmon can carry parasites and an enzyme that destroys vitamin B1; and bones, salt and seasonings must go. Like tuna, some cats become so keen they start snubbing their normal food.
A teaspoon to a tablespoon of plain cooked, boneless salmon once or twice a week as a treat or topper. Skip smoked salmon (salt) and anything cooked with onion, garlic or butter. Introduce gradually.
