Buying advice

When selecting a cat fish oil supplement, verify it is specifically made for cats (correct dosage) and check the source of fish (wild-caught is preferable). Look for products with high EPA and DHA levels, and consider your cat's taste preferences. Always consult your vet before starting any supplement.
