What is the best immune support for cats?

The best immune support for cats is a healthy diet and lifestyle, but there are many supplements you can give your cats to help boost immunity, too. Your vet may be able to recommend some good supplements for your kitty, or you can find immune supplements formulated to target specific health issues your cat is having. Chewy has a great selection of immune supplements for cats, including cat allergy supplements, supplements that help cats fighting infections, calming supplements, digestive supplements and more.

What can I give my cat for allergies?

You can give your cat a variety of things for allergies, but you should consult with your vet to get the best guidance and rule out serious health problems first. Depending on what kind of allergies your cat has, your vet may recommend a skin and coat allergy supplement for cats, a respiratory supplement for cats, or an immune supplement with L-lysine, probiotics or other immune-boosting compounds.

How can I boost my cat's immune system?

You can boost your cat's immune system by feeding a healthy diet, encouraging healthy exercise and minimizing stress that can wear your cat's natural defenses down. Cat immune supplements are another way to give your cat's immune system a healthy boost, and there are many types to choose from. Talk to your vet about what immune supplements might be best for your cat and check out the wide range of choices available on our site.

Do cats actually get seasonal allergies?

Many cats do actually get seasonal allergies, and allergies can be as unpleasant for felines as they are for us! The good news is that there are many ways to help cats with seasonal allergies, including medicines and antihistamines prescribed by your vet and over-the-counter cat allergy supplements.
