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!

Best joint supplement for a 5-month-old kitten with fragile bones?

Hi and thanks for posting on Boop by Petco! The first thing I'd make sure Willow is eating is enough calcium. Be sure Willow is eating a kitten food until she is about 9 months to a year of age as kitten food has more calcium and other minerals in it that is required for healthy bone growth. A great supplement you may want to consider is DHA and EPA. Both are types of omega 3 fatty acid that are excellent for healthy development for multiple organ systems such as the heart, brain, skin, and bone/joint health. I have a product I'd recommend below: https://www.petco.com/shop/en/petcostore/product/vetri-science-laboratories-omega-3-6-9-dog-and-cat-gel-caps# I hope this helps!

Cat with cancer only eats tuna. What diet or supplements are best?

VetriScience NuCat Multivitamin Everyday Health Bite Sized Chews available on chewy.com and amazon.com are highly palatable multivitamins that would be good to supplement Greg’s diet with. Prescription Royal Canin recovery canned diet is generally palatable (yummy) to even sick or hospitalized cats and is another option as well that your vet can either sell from his/her practice or prescribe. Good luck!

My 12-year-old cat has arthritis. What joint supplements help?

Hello, if your kitties are eating a brand name cat food well, then vitamin supplementation is neither necessary or advised. For arthritis, however, I strongly recommend starting a glucosamine supplement. Nutramax makes one called Cosequin, which I use & recommend to all of my elderly cat patients. It comes as a capsule that you can pill them with, or just open the capsule & sprinkle the contents on a little moist food. If your cats are very arthritic, then talk with your veterinarian about starting Adequan injections. They really help the joints, too. Thank you for using Boop by Petco.

Is human lysine safe for cats? My vet prescribed it, but it's costly.

I would also like to add that sourcing is a big issue for supplements. Apart from the palatabity, some companies are better than others. If you choose this route, make sure you speak with someone in a supplement specialty store about reputation. Since there is no governing body for supplements, contaminants are possible.
