Many humans suffer from allergies, but they don’t realize that cats can get allergies too. Allergies are main causes of skin diseases in cats. The term allergy means "altered working". The immune system is designed to keep infectious pathogens, such as bacteria, viruses, and fungi, out of the body, and to destroy any pathogens that attack the body. However, in an allergic animal, the immune system overreacts to harmless substances. Here you can find several solutions when you don't know and want to ask, "what can I give my cat for allergies?"

Try Some Natural Remedies

Natural remedies may help when you are wondering, "what can I give my cat for allergies?"

  • Fatty Acids: Omega 3 fatty acids work by decreasing the overreaction of your cat’s immune system. While omega 3 fatty acids can be effective for some cats, it takes about 3 to 6 weeks to take full effect—so you’ll need to be patient. Additionally, in order to work properly, your cat will need to consume same amount of omega 3 and omega 6 fatty acids in their diet.

  • Yucca: Yucca is a natural anti-inflammatory medication that can assist the immune system to work properly. Yucca should be given to your cat daily, and may be applied either directly to their skin or mixed into their food.

  • Topical Therapy: Topical therapy can also be helpful for cat with allergies. Some options for topical therapies include colloidal oatmeal , hypoallergic or hydrocortisone shampoos. Hydrocortisone creams or salves can also help, but these medications should not be used on areas that cats are able to lick.

Medical Treatment for Cat Allergy

Caution: If you are wondering, "what can I give my cat for allergies?" Do not give your cat medications unless prescribed by a veterinarian.


Antihistamines are very common medications that used for treating allergies in both pets and humans. These medications are effective in 70% of cats, and even more effective when the cat be treated with fatty acids as well and follow avoidance suggestions mentioned above. Antihistamines that are commonly used in cats include diphenhydramine, hydroxyzine, clemastine, and chlorpheniramine. Antihistamines should not be given to your cat unless recommended by your veterinari. Some side effects of antihistamines include sedation, hyperactivity, dry mouth, constipation, and decreased appetite. 



Steroids are an extremely effective medication for cats with severe allergies and itching. However, these medications do have some severe short-term or long-term side effects, so they should be used with caution and at the lowest possible dose. Steroids are usually reserved for use when other treatments don't work. Steroids may be given either orally or as an injection. The most common side effects of steroids in cats include increased hunger and thirst, increased urination and diarrhea.



Immunosuppresants, such as cyclosporine, may be used as an alternative to steroids in cats. They are usually quite effective, but they are expensive and have side effects including loss of appetite and rarely bone marrow suppression.



Specialized, customized shots designed to protect your cat from specific allergens are called immunotherapy. Immunotherapy can only be used after your cat has had an allergy test to detect their specific allergic triggers.
