Cat-scratch disease, also known as cat-scratch fever, is a bacterial infection transmitted through cat saliva. It is not considered a severe infection in those normally considered healthy but it can be a problem to those with weak immune systems. While cat-scratch disease can effect people of any age, it is most commonly observed in children.
Cats transmit the bacteria to humans through their saliva. This transfer can take place from a cat bite or scratch. Petting a cat with the bacteria, and then rubbing your eyes, may also transfer the disease. The disease is more common in kittens, or young cats, than in older felines. It is estimated that approximately 40% of cats have carried the bacteria at some point in their lives.

Symptoms of cat-scratch disease include:

A brownish bump, or sore, where a cat has bitten or scratched.
The site of the scratch or bite does not heal as quickly as anticipated.
A low-grade fever that last for several days after receiving a bite or scratch.

Swollen, tender and possibly painful lymph nodes. Usually near the site of injury (for 2-3 weeks or more).

Bone, joint or abdominal pain (for 2-3 weeks or more) Headache

Fatigue (for 2-3 weeks or more)

Poor Appetite The disease often clears without treatment but does usually 2 - 4 months. Antibiotics may be administered in severe cases or for those with weak immune systems. Lymph nodes may be treated with a warm, moist compress to ease swelling and pain. If your lymph nodes are especially large and painful, your doctor may choose to drain them to alleviate the pain.

Avoid playing roughly with your cat as this may entice them to scratch or bite. Be especially careful with kittens. Wash your hands after handling cats and immediately wash any cat bites or scratches. While the cause of the bacteria is unknown, research does point to fleas as a possible source. Provide flea prevention for your cat and get rid of any fleas as soon as possible. Cats only seem to be able to transmit this infection for a few weeks. Young cats seem to be more likely to carry the bacteria than older cats. Households with kittens have higher rates of infection. If the kittens have fleas, the infection rate is even higher.

Your cats do not need to be treated for the disease. It does not harm them and they will not exhibit any signs of being infected. Play carefully and wash any wounds immediately. You and your cat should be able to live a happy, cat-scratch disease free life.
