Seven Common Causes of Hair Loss in Cats

Usually, it’s pretty noticeable when a cat starts to lose his hair. If you notice your pet’s beautiful coat of hair falling out, it may be a cause for concern. Here are some of the most common causes of hair loss in cats.

Hair Loss


Cats can develop various types of dermatitis. Contact dermatitis, one of the common causes of feline hair loss, can be caused by various things in your cat’s environment. Carpet deodorizer, various chemicals, and even wool can all lead to contact dermatitis among other things. Medications that are applied to the skin may be the problem.


Hyperthyroidism is a disease that generally leads to hair loss in cats. The thyroid gland is responsible for pumping out different types of hormones for various functions. Problems occur whenever it produces too few or too many, as is the case with hyperthyroidism. Potential treatments include removing part of the thyroid gland, daily medications, or radioactive iodine therapy.


What you feed your cat can be the reason his hair starts to fall out. Cats can develop sensitivities to certain ingredients over time. To help see exactly what foods may be the problem, the vet may place your cat on a food elimination trial over two or three months.


Ringworm is a highly contagious infection that’s caused by a fungus, not a worm. Hair loss in cats caused by ringworm will have circular, patchy shapes. The affected areas will also turn red and be quite itchy to your cat.

If you have other pets in your home, you will need to keep them away from the one with cat ringworm. You would also need to disinfect all surfaces your cat came into contact with, and ideally toss out all bedding.


An infestation of fleas doesn’t just cause your kitty to itch. Feline hair loss can be caused by sensitivity to flea bites. This type of reaction can develop over time. A combination of antihistamines and steroids will alleviate your cat’s itching and the hair will grow back over time. In the meantime, you will need to implement effective flea control methods for your cat’s environment.


There are many different species of lice. Those that affect cats cause typical symptoms such as itching and a rough coat of hair. As the situation worsens, hair will start to fall out and crusts will develop in the affected areas. Giving your cat a bath with medicated shampoo should be enough to get rid of the problem.


Just like with humans, chemotherapy has a number of ill side-effects. One of the most common is hair loss in cats. Although your cat won’t look any better on the outside, hopefully the chemotherapy medications will do the job they were designed to do. After your cat stops taking them, his hair will start to grow back. However, it may not be the same as it was before.

As you have learned, there are many different causes of cat hair loss. If you notice any changes in your pet, it is best to let your vet take a look.

Feline Diarrhea

Diarrhea in cats is not a disease, but merely a symptom of an underlying disease. You should be aware that persistent diarrhea can cause severe dehydration. Dehydration will rob your cat of essential fluids and nutrients which can prove to be fatal if not treated in time.

Feline Diarrhea


There are numerous things that can cause feline diarrhea. Cats who consume something they’re not supposed to may develop the condition. Viruses or parasites that affect the intestinal tract or stomach can also cause diarrhea. There are plenty of diseases that can cause it as well. Some of the most common include hyperthyroidism, leukemia virus, inflammatory bowel disease, and immunodeficiency virus.


Cats who experience a mild case of diarrhea will likely just have loose stool. However, major diseases that cause the condition may lead to other symptoms such as vomiting, appetite loss, fever, and lethargy. The stool may also be bloody. Some cats also experience abdominal pain and the aforementioned dehydration.


It is important for the vet to determine what is causing the case of feline diarrhea. This is done by taking a complete medical history and performing a thorough physical examination. The vet will also have the stool checked for the presence of bacteria or parasites.


Once the veterinarian has determined what is causing the condition, he can begin treatment accordingly. Electrolytes and fluids will need to be replaced in the event of dehydration. Antibiotics or other special medications may need to be prescribed to treat the underlying disease. Some cats may need a change in diet or even surgery to correct the problem.

Feline Diabetes

Diabetes is a relatively common condition in cats. It usually affects older or obese cats, although any cat can be affected. Feline diabetes can’t be cured, but it can be effectively managed over time so your cat can lead a normal life.

Feline Diabetes


Diabetes in cats affects males more often than females. Veterinarians don’t know the exact reason felines develop the condition. However, there are certain conditions that can increase the risk. They include chronic pancreatitis, hyperthyroidism, Cushing’s disease, and obesity. Cats taking certain medications may also develop the disease.


There are two different types of feline diabetes. They include insulin-dependent and non-insulin-dependent. Cats who are insulin-dependent will require injections, but non-insulin-dependent cats may not require immediate injections although they may develop the need to over time.


Diabetes in felines is diagnosed based on a physical examination. Your veterinarian will also need to perform laboratory tests. These tests will show an increased level of sugar in the urine and blood.


Feline diabetes causes various symptoms. They include increased urination, increased thirst, and weight loss. It’s also common for cats to develop a poor coat of hair. Other common signs include increased or decreased appetite, lethargy, and depression.


Diabetes in cats will shorten the lifespan if left untreated. Insulin injections are the most common treatments. There are different types of insulin and different cats may respond to different types. Some cats can effectively be treated via use of oral medications.


There is no cure for feline diabetes. However, cats with the disease can live a normal and healthy life for many years. Cats may even lose the need to receive insulin injections over time. If obesity is the underlying cause, losing weight will help dramatically.

Feline Kidney Disease

Although it can affect younger cats, feline kidney disease is normally a problem with older cats. This condition can occur suddenly known as acute, or develop over time and be classified as chronic. Since the kidneys are responsible for eliminating toxins from the body, damage to them is very serious.

Feline Kidney Disease


There are many different things that can cause kidney disease in cats. Your cat’s kidney function will naturally decrease with age. Also, felines that don’t have enough potassium in their diet are at risk.

There are also different types of drugs that can lead to feline kidney disease. They include blood pressure medication, anti-parasitic drugs, anesthetics, and antibiotics. Chemicals such as pesticides and antifreeze can also cause the condition.


Your cat’s kidneys have a large reserve capacity. This means that symptoms won’t be noticeable until up to 75% of the organ is damaged. Common signs include increased urination and drinking. Your cat will also lose the ability to concentrate his urine.

As feline kidney disease progresses, toxins will start to build up in the body. This leads to oral ulcers, depression, loss of appetite, and vomiting. You may also notice that your cat’s breath has a foul odor. In the later stages of the disease, seizures may develop.


There are other diseases that cause symptoms similar to those of kidney disease in cats. Two of the most common include hyperthyroidism and diabetes. In order to diagnose this condition, your veterinarian will need to perform urine and blood tests.

A urinalysis will show the inability to concentrate urine. An x-ray may also show that the kidneys are irregular or shrunken. The veterinarian may also perform an ultrasound or palpate the kidneys.


As the kidneys become damaged, uremic toxins will buildup instead of being secreted. Therefore, your cat will need a special diet and plenty of fluids. Cats are normally given fluids intravenously on a regular basis over time.

Since certain medications can cause feline kidney disease, they will need to be stopped. Cats with this condition will need a low protein diet. They can also develop anemia and require blood transfusions.
