Despite common belief, an average cat experiences only minor skin irritation in response to flea bites. Even in the presence of dozens of fleas, there will typically be minimal itching. On the other hand, a cat with flea allergies will have a severe reaction to even a single flea bite. Affected cats experience intense itching and will chew, lick, or scratch the affected site(s) nonstop, causing hair loss and possibly open sores or scabs on the skin, allowing a secondary bacterial infection to develop. Strict flea control is the foundation of successful treatment. There are many highly effective flea control products for treating the cat and controlling fleas in the environment.

Flea allergy dermatitis is a common cause of allergic reactions in dogs. The antigens in flea saliva cause an intensely itchy response in sensitive dogs. Itching and hair loss in the region from the middle of the back to the tail base and down the rear legs (the flea triangle) is often associated with this allergy. Strict flea control is essential for treatment and prevention.

Feline miliary dermatitis is a skin condition that typically results from an underlying allergic reaction, most commonly to fleabites. An affected cat will have a very itchy rash and may lick, bite, and scratch at the affected skin, quickly progressing to small lesions with scabs on them. The offending allergen must be removed for long-term resolution.

An allergy occurs when the cat's immune system overreacts or is hypersensitive to foreign substances called allergens. There are four main types of allergies in cats, namely flea allergy, atopic dermatitis (atopy), food allergy, and contact allergy. They share common physical expressions and signs in cats, and each has unique features.

Ferrets commonly develop skin diseases, including infections with parasites (fleas, mites, ticks), bacteria, viruses (distemper), and fungus (ringworm). They are also subject to both benign and malignant tumors, including mast cell tumors. Adrenal tumors also cause hair loss and itchy skin in ferrets. All skin problems should be brought to the attention of your veterinarian, who will recommend the most appropriate treatment for the specific problem.

Staph (or staphylococcal) dermatitis is an inflammatory skin condition that the skin caused by a group of bacteria called Staphylococcus. Any disorder that causes itching or a change in the skin’s environment can create the ideal conditions to allow Staphylococcus to become a problem. This handout discusses Staphylococcus dermatitis in dogs, as well as a hypersensitivity (allergic) reaction to this bacteria. The clinical signs of these conditions, along with diagnosis, treatment, and prognosis, are outlined.

This handout discusses atopic dermatitis (atopy), a form of allergic skin disease brought on by an abnormal response to allergens in the environment. The clinical signs, diagnosis, and treatment are outlined.

Bee stings and bites from spiders, fleas, and ticks are the most common causes of insect bite reactions in pets. Insect bites can cause mild to severe allergic reactions in many dogs. Fortunately, most reactions are minor and have an excellent prognosis for recovery. Treatment typically involves antihistamines and anti-inflammatory drugs.
