Yes, cats can eat salmon. Salmon is a good source of protein and omega-3 fatty acids, which can be beneficial for a cat's health. However, it's important to feed salmon to cats in moderation and only as a part of a balanced diet. Feeding too much salmon or feeding it too frequently can lead to health issues such as obesity, digestive upset, or even mercury poisoning if the salmon is contaminated. Additionally, it's important to avoid feeding raw or undercooked salmon to cats, as it can contain harmful bacteria and parasites that can cause food-borne illnesses. Therefore, it's best to cook salmon thoroughly and remove any bones before feeding it to your cat. If you have any concerns or questions about your cat's diet, it's recommended to consult with your veterinarian for personalized advice.
