How Can Mosquitoes Bite Cats?

Whether you live in a hot climate or one with a rainy season, you are at risk for mosquitoes. They are known to infect a wide variety of animals, including cats, and can carry a number of parasites and diseases. If your cat is bitten by a mosquito, it is important to identify the symptoms and seek veterinary care.

The first signs of a mosquito bite are often itchy, red, or inflamed lesions. These may look like crusty areas, scabs, or raw ulcers. A cat with a true hypersensitivity response may also have enlarged lymph nodes and a fever. The veterinarian will perform a skin biopsy to determine the nature of the infection. If the problem persists, immunosuppressants or other treatments might be needed.

When a cat is bitten by a mosquito, the specialized antibodies in the immune system react by engulfing the allergen. White blood cells then produce an inflammatory response, which causes redness, swelling, and itching.

Some cases of hypersensitivity are mild and will resolve on their own. However, more severe cases can result in hair loss and ulcers. A vet will prescribe a medication to stop the reaction and treat the infected area.

In most cases, a vet will suggest that you isolate the cat from the source of the infestation. This might mean a week or more in an indoor environment.

If your cat has a severe hypersensitivity reaction, it might require oral or systemic glucocorticoids to reduce the inflammation. The vet might also recommend a skin biopsy to determine the nature of your pet’s reaction.
