| Flea Allergy Dermatitis (FAD) is the most common allergy in pets. It is caused by flea bites and can leave your cat’s skin very itchy and prone to skin infections. Cats affected by FAD are not necessarily infested with fleas, as one single bite can cause an allergic reaction. What are the symptoms of FAD?
FAD is considered a seasonal allergy, as are fleas. Symptoms worsen during peak flea times during the summer and the fall. Symptoms to watch for include: - Itching
- Chewing
- Hot Spots
- Red Bumps on the Skin
- Skin Lesions
- Hair Loss
How is FAD diagnosed?
The visual signs usually diagnose FAD, as well as if there are also fleas present on your cat. Some veterinarians might also do skin allergy testing. How is FAD treated?
The best treatment for FAD is keeping your cat flea free. This can be done with a topical flea spot on, such as Frontline Plus or Advantage Flea Control. You will want a product that not only kills fleas, but repels them also. Remember, you want to keep your pet from being bitten. Occasional flare-ups can be treated with antihistamines, such as Chlorpheniramine or Benadryl. More severe cases may be treated with cortisone ointments or injections. Cats that develop a secondary skin infection from scratching may be treated with a round of antibiotics such as Cephalexin, Baytril or Clavamox. How can I help prevent FAD?
The most important thing to do is keep your house and your pet flea free. For tips on keeping your home flea free, please see our article titled How to Keep Your Pet and Your Home Flea Free. You can also bathe your pet several times a week using cool water and a gentle shampoo, such as Natural Oatmeal & Aloe Vera Shampoo. Do not use warm water, as it can dry the skin and intensify any itching your pet might be experiencing. |
