Unfortunately, it’s hard to stop cat allergies, especially if you don’t know what your cat is allergic to. Cats are curious by nature, which makes it even harder to control.

But you can lower the risk by:

You can help lower your cat’s allergy risks by:

• Keeping your cat indoors to limit exposure.

• Talking to your vet about:

  • Possible side effects of medicines.

  • What to do in an emergency (for example, bathing a cat right away if they have allergic skin problems).

  • Whether splitting vaccines or giving diphenhydramine before vaccines is a good idea.

• Checking your cat often. Look for bumps, insect stingers, or small wounds so you can get help quickly.

• Avoiding known allergens. Each exposure can make the reaction worse.

• Using strict flea control. Fleas can trigger strong allergic reactions.

• Following a vet-recommended diet and not changing food without advice.
