There are a number of common cat medical problems which every cat owner should be aware of. They range from severe conditions to minor annoyances.


Hairballs form in the cat's stomach as a result of the routine licking of its fur. They are not normally a problem but can become one if they obstruct the cat's digestive system. Symptoms include loss of appetite, diarrhea, and problems defecating.


Fleas can be a great nuisance to cats and cause frequent scratching, rashes, and loss of fur. Many sprays, powders, and flea collars are available to control these annoying pests.


Ticks will attach themselves to your cat's skin and drain blood. They can spread diseases, such as lyme disease. They can be very tiny, and remain attached until engorged on blood. It is often at this point that they are detected, as they tend to grow larger and more noticeable at this stage. Grasp them just above the skin with tweezers and pull gently, but firmly, until they release. Applying an antibiotic to the bite will help prevent an infection.


Worms are among the most common of cat medical problems, especially in outdoor cats. They enter your cat's body through ingestion of tiny eggs. They can cause loss of appetite and nutrients. They are sometimes visible in the cat's stool. Veterinarians have a variety of medications available to completely eliminate these parasites.

Cat Ring Worm

In spite of its name, ring worm is a not a worm at all, but a fungal infection of the skin. It can cause itchiness and hair loss. It is highly contagious and can spread between cats and humans.


Cat medical problems include conjunctivitis. It is caused by an infection of your cat's eyes. It causes the eyes to turn red and swollen, and produces a runny, milky discharge. Your cat's vet will prescribe eye drops which will clear up the condition.

Urinary tract infections

This is one of the more common types of cat medical problems. You may first notice this when your cat has difficulty urinating. The vet will prescribe something to clear it up, depending upon whether the condition is bacterial, fungal, or parasitic in nature.

Feline Leukemia Virus

Feline Leukemia Virus is an extremely serious, contagious disease. If you suspect your cat is infected, separate it from any other cats in your household, and contact your vet immediately.
