My cat's fur is dull and shedding. What vitamins or supplements help?

Hi and thank you for your question on Boop by Petco! Omega 3 & 6 Fatty Acids can help quite a bit with hair and skin health. B vitamins (B12, B5, B9) can also help with skin and coat health. Vitamin E can also help. I would acquire these supplements from your veterinarian. Here's a good supplement on amazon: https://www.amazon.com/Theracoat-Skin-and-Coat-Supplement/dp/B005FYOCQ4 I hope this helps!

What fish oil supplements are best for my cat's dry skin and dandruff?

Hmmm. Not sure the train of thought your vet was on. I commonly recommend fish oils, any fish oil supplement will work. There is no specific amount, though the biggest side effect is greasy stools. If you notice that, then you decrease the dose. It can take several months for you to see a change after starting fish oils. You can find a pet product at a pet store, or just use one from the human supplements section of a pharmacy or other store.

My cat sheds a lot. What cod liver oil or supplements are safe?

Cod liver oil contains a large proportion of vitamins and minerals which can be difficult to adjust in small dosages. A blended omega fatty acid supplement formulated specifically for cats is preferred such as viacutan, omega aid or vitacat. Other options are specialist skin diets such as hills or royal canin which are additionally supplemented with natural antiinflammatory and coat conditioning ingredients

My cat is shedding a lot and has dandruff. What food or supplements?

I would recommend the Duoxo shampoo (seborrhea if it is dry flaky skin, available online) and pet formulated fish oils from your local pet store. The shampoo will help exfoliate her follicles and the fish oil is a natural anti-inflammatory. Ask your local sales rep to point you towards what options they have as far as fish oils go. They are all pretty much equivocal. I would also consider having her thyroid levels tested and baseline bloodwork analysis done to ensure there are no underlying causes for her unhealthy appearing haircoat. Best wishes with managing The Messaiahs skin.

Can fish oil help my cat thrive? What's the proper dosage?

If she is on a high quality, balanced diet I would be cautious about over supplementing her as this can lead to dietary excesses (especially with cod liver oil type supplements as they can be high in certain vitamins also). Plant based supplements such as viacutan may also be an option but 3-5 days a week is likely sufficient
