What Are the Most Common Cat Diseases?

5 Cat Diseases Decoded: How To Diagnose, Treat and Prevent Each

Cat illnesses can be worrying for any cat owner, but the good news is that many of them are preventable.

Vaccinations are a great way to protect your cat from diseases like feline parvovirus and FeLV.

Regular booster shots will ensure your cat stays healthy and safe from these common ailments. A balanced diet is also important for keeping your cat healthy.

Overweight cats are more likely to suffer from conditions such as diabetes or arthritis, so make sure you’re feeding them the right food and giving them plenty of exercise too!

Regular worming and flea treatments should also be given to keep parasites at bay.

It’s best to get these treatments from your vet, as they will have the most effective product for your individual circumstances; some ‘off-the-shelf’ products may not be very effective or even harmful for cats.

If you do notice any changes in behavior or physical appearance in your pet, then it’s always best to seek advice from a qualified veterinary professional who can diagnose any underlying issues quickly and accurately, ensuring that treatment is administered swiftly if necessary.

Let’s take a closer look at some of the most common illnesses in cats.

1. Feline Leukemia Virus (FeLV)

One virus that can affect cats is the feline leukemia virus (FeLV). This virus can cause a variety of health problems in cats, including anemia and cancer.

FeLV is spread through contact with saliva or other bodily fluids from an infected cat. It can also be passed on to kittens by their mother before they are born or while nursing.

Common symptoms of FeLV include fever, loss of appetite, weight loss, pale gums, respiratory infections or urinary tract infections, diarrhea, and vomiting.

If your cat exhibits any of these signs, take them to the vet immediately.

Unfortunately, there is no cure for FeLV, but there are treatments available to help manage the symptoms and improve the quality of life for affected cats.

If your cat tests positive for FeLV, it’s important to stop further transmission of the virus.

  • Keep your cat indoors at all times.
  • Have regular checkups with your vet.
  • Vaccinate all other cats in the household against FeLV.
  • Separate infected cats from non-infected ones.
  • Feed a high-quality diet rich in vitamins and minerals to boost immunity.
  • Give supplements like omega-3 fatty acids, which have been shown to reduce inflammation associated with viral diseases like FeLV.
  • Provide plenty of love and attention.

2. Feline Immunodeficiency Virus (FIV)

Feline Immunodeficiency Virus (FIV) is a retrovirus that affects cats and can cause serious health issues if left untreated.

FIV attacks the immune system of cats, making them more susceptible to other illnesses and infections.

Symptoms of FIV include fever, loss of appetite, weight loss, poor coat condition, and eye discharge. In some cases, there may also be neurological signs such as seizures or behavioral changes.

It’s important to note that while there is no cure for FIV, there are ways to manage the disease and help your cat live a long and healthy life.

Your veterinarian will likely recommend regular check-ups with blood tests so they can monitor your cat’s progress over time.

Additionally, providing good nutrition along with plenty of exercise will help keep their immune system strong enough to fight off any additional illnesses or infections they may encounter in their lifetime.

If you suspect your cat has been exposed to FIV or are concerned about any symptoms they may have developed, it’s best to contact your vet right away.

3. Upper Respiratory Infections

One of the most common illnesses in cats is an upper respiratory infection (URI).

URIs are caused by viruses and bacteria that affect the upper airways of cats, such as their nose, throat, and sinuses.

The most common symptom of URI is a runny nose, but other symptoms can include watery eyes, sneezing, and fever.

In some cases, URIs can lead to more serious health problems, like pneumonia.

It’s important to take your cat to the vet if you suspect they have a URI so they can receive proper treatment.

Fortunately, there are several ways to help prevent your cat from getting a URI in the first place.

  • Vaccination: Make sure your cat is up-to-date on all their vaccinations, as this will help protect them against many different types of infections, including URIs.
  • Good hygiene practices: regularly clean out litter boxes and bedding areas with hot water or disinfectant products to reduce the spread of germs between cats living in multi-cat households.
  • Avoid contact with sick animals: If possible, avoid contact with other cats who may be carrying infectious diseases that could potentially infect your own pet.

If your cat does get sick, there are many effective treatments available, depending on what type of virus or bacteria has caused the infection.

Your vet will advise you on what course of action is best for treating your cat based on test results and clinical signs observed during the examination.

4. Ear Mites

Ear mites are most commonly found in the ears, but they can also be found on other parts of the body.

Ear mites cause irritation and discomfort for cats and can lead to secondary infections if not treated properly.

Symptoms of ear mite infestation include:

  • Excessive scratching or shaking of the head.
  • Discharge from the ears that may appear dark brown or reddish-brown.
  • Unpleasant odor coming from inside the ears.
  • Inflammation around the ears or face.
  • Hearing loss due to damage caused by ear mites.

The good news is that there are treatments available for ear mite infestations in cats.

The first step is to take your cat to a veterinarian, who will examine them and prescribe medication if necessary.

This could include topical medications such as ointments or sprays applied directly to their ears as well as oral medications.

It’s important to follow all instructions given by your vet when treating common illnesses in cats, so they get better quickly.

Make sure your cat has access to clean bedding and is regularly groomed with a flea comb. This helps remove any debris from their fur, which could harbor parasites like ear mites.

Also, make sure you keep up with regular cleaning routines such as vacuuming carpets (especially where your pet sleeps) since dust particles can carry parasites too.

5. Ringworm

Ringworm is a common skin infection that can affect cats as well as humans and other animals.

It’s caused by a fungus called dermatophytes, which feed on the dead layers of skin cells found in fur or hair follicles.

While it’s not life-threatening, ringworm can cause uncomfortable symptoms for your cats, such as itching, redness, and scaly patches of skin.

Cats usually get ringworm from contact with an infected animal or a contaminated environment.

The fungus is also very contagious to humans, so if you suspect your cat may have ringworm, take precautions when handling them!

The most common symptom of ringworm in cats is patchy bald spots. Your cat may also experience intense itching, which could lead to excessive grooming or licking.

Other signs include thickening of the skin (hyperkeratosis) and crusting around lesions that are present on the body.

If you think your cat might have ringworm, see a vet right away; don’t wait until things get worse!

Treatment typically involves topical or oral antifungal medications. There are also home remedies, such as coconut oil, that can help reduce inflammation associated with fungal infections.


Understanding and recognizing common cat diseases is crucial for every cat owner.

By staying informed, seeking regular veterinary care, and providing a safe, clean environment, you can help protect your feline companion and ensure they lead a long, healthy life.

Remember, knowledge is the best defense against these potential threats, and your cat’s well-being is worth every effort.
