Is Fish Oil Good for Cats?
Fish oil contains omega-3 fatty acids (mainly EPA and DHA). Veterinarians often recommend omega-3s to support skin and coat health and to help manage inflammation-related issues in some cats.
The right fish oil dosage for cats depends on your cat’s weight and the product’s strength. Some products list total fish oil mg, while others list EPA + DHA mg. This calculator provides a simple daily mg estimate based on body weight.
If your cat has a health condition or takes medications (especially blood thinners), ask your veterinarian before starting fish oil.
