Fish oil meant for humans can be given to cats because it contains many nutrients that can help improve a cat's coat and reduce shedding.

However, it's crucial to be careful with the dosage of fish oil. Never give your cat an excessive amount, as this can cause vomiting. Therefore, it's best to include fish oil in your cat's daily diet and carefully observe their reaction. If any abnormalities occur, it's recommended to seek veterinary attention immediately.
