Raw salmon can carry harmful bacteria like Salmonella and parasites, and contains thiaminase which destroys essential Vitamin B1. Cats should never consume raw fish.
Canned light tuna in water is a safe, high-protein snack when given sparingly. However, it lacks complete feline nutrition and contains trace mercury, so it must not replace balanced cat food.
Tuna packed in oil contains excessive dietary fats and calories that can trigger digestive distress or pancreatitis in cats. Oil packing also leaches nutrients away from the fish.
