Can I Give My Cat Welactin?

Yes, with care
Fish oil (EPA + DHA) is commonly referenced for cats at published doses. The published veterinary reference range for fish oil (epa + dha) in cats is 20-40 mg per kg of body weight, given every 24h. In practice: combined EPA+DHA per kg daily. Avoid cod liver oil (vitamin A/D overload).

About Fish oil (EPA + DHA)

Fish oil (EPA + DHA) is a supplement rather than a drug, which still deserves the same dosing care. You will see it sold as Welactin, Nordic Naturals Pet and store-brand equivalents, and the label strength on the box is what matters for the math, not the brand. Reference data on this page reflects published veterinary sources, not a prescription for your cat.

What to have ready when you call the vet

Whether you are confirming a dose or reporting that your cat already got into something, the call goes faster with four facts ready: your cat's current weight, the exact product name and strength from the label, how much was given or eaten, and roughly when. With those, most clinics can answer in one call.

The safe habit

Confirm any medication decision with your veterinarian, who knows your cat's health history and other medications. VetDose shows published reference data, not prescriptions.
