Cats can and do often suffer from a wide range of allergies. In fact, 15 percent of all cats in the United States suffer from one or more allergies, according to the Society for the Prevention of Cruelty to Animals. Fortunately, there are treatments available.
While antihistamines are not reliable solutions to allergies in dogs, they have shown positive results controlling allergies in cats. They are often used in conjunction with a corticosteroid hormone to reduce itching.
In some cats, long-term steroid injections offer the only effective allergy control substance. These treatments, often in the form of Depo-Medrol injections, are becoming more common for cats suffering multiple allergies.
Fatty Acid Supplements
Evening primrose oil and fish oils have shown anti-inflammatory properties in humans. Similar products are now available for pets to reduce joint pain, cramps and itchy skin. While it does not eliminate the allergy, it is effective at treating the symptoms.
In limited instances, hyposensitization can be used to treat allergies in cats. The treatment introduces the specific allergen to the cat in increasing quantities over time. It is usually introduced as an injection and requires knowing exactly what the cat is allergic to.
Topical Itch Creams
Corticosteroid creams are effective at treating itching, a common symptom of allergies. However, because the topical cream can be absorbed through the skin and into the blood stream, it is recommended by veterinarians that the creams be used only on small, isolated areas.
