Just like people, individual cats have different blood types. Most domestic cats have type A blood, but purebred cats, like your Himalayan often have a different blood type, usually type B or very rarely, type AB. Determining your cat’s blood type is essential before starting a transfusion, so knowing your cat’s type ahead of time can save crucial minutes. Blood typing is recommended for all cats, but is especially important for purebreds. This test can be done as part of a routine wellness blood testing, and the results can be added to your pet’s microchip record as well for fast action even if you aren’t there.

Neonatal Isoerythrolysis (NI)/Hemolytic Icterus

Neonatal isoerythrolysis, or NI, is a rare immune-mediated disease that is caused when a newborn kitten with type A blood suckles colostrum (first milk) from a mother with type B blood or vice-versa. The mother’s immunity against type A blood is contained in her colostrum, so when the kitten nurses, the antigen is absorbed into the kitten’s bloodstream through ingestion. The resulting immune reaction develops antibodies that attack and destroy the kitten’s own red blood cells. Consequently, affected kittens usually die within a few days of birth. NI can occur in many cat breeds, but is more often seen in breeds with a higher likelihood of having type B blood like your Himalayan. If you plan to breed your cat, you will need to learn more about this problem beforehand from your veterinarian.

Portosystemic Shunt

Portosystemic shunt is a disorder seen occasionally in cats, in which some of the blood supply to the liver is shunted around it instead. This condition deprives the liver of the full blood flow it needs to grow and function properly, leading to an undersized, poorly nourished liver that cannot fully remove toxins from the bloodstream. These unfiltered waste materials, such as ammonia and bile acids, eventually build up in the bloodstream and act as poisons to the body’s systems. For example, in severe cases, high blood-ammonia levels can cause neurological issues. Cats affected by a portosystemic shunt are also extremely sensitive to drugs and anesthetics, as the liver cannot efficiently cleanse the bloodstream of the added chemicals. If your cat shows symptoms of a portosystemic shunt, we will perform blood testing or a liver ultrasound scan can to check for the disorder. In some cases, surgery can restore proper blood flow to the liver.

Cutaneous Asthenia (Ehlers-Danlos)

Ehlers-Danlos syndrome is a rare genetic problem that that causes abnormal collagen and connective tissue development. It occurs in many types of mammals, including cats, dogs, and even humans. Connective tissue holds all the parts of the body together—if the connective tissue is faulty, then parts that should be joined together tightly in the normal body will have weak and very elastic connections. This condition leads to unstable joints and legs as well as very stretchy skin. The skin will tear very easily and wounds heal with difficulty. Problems with the eyes, veins, arteries, and heart valves are common with this syndrome as well. The severity of the condition can vary; severely affected kittens usually will not survive past adolescence, but kittens with a mild form can generally live into adulthood. Cats affected with cutaneous asthenia should never be used for breeding.

Peritoneopericardial Diaphragmatic Hernia (PPDH)

PPDH is an uncommon, inherited defect that occurs when the diaphragm doesn’t form properly. The diaphragm normally creates a barrier between the chest cavity and the abdomen, so a malformation can result in the tissue sac that surrounds the heart being connected to the tissues of the abdomen. Because of this defect, organs that should be enclosed inside the abdomen may be squeezed through the opening in the diaphragm into the chest cavity. If the hernia in the diaphragm is small, organs may not be able to pass into the chest, but if they do, the cat will show sudden vomiting or respiratory distress, which can come on rapidly and at any age. If PPDH is confirmed, surgery is needed to replace the abdominal organs and to close the defect. Affected cats and their relations should not be used for breeding as PPDH is genetic.

The thyroid glands rest on both sides of the neck alongside the windpipe.


The thyroid gland is located at the front of the throat, and has a very important function. It produces a hormone called thyroxine, or T4. Thyroxine regulates the overall speed of metabolic processes throughout the body. Cells in every part of the body start to work faster when T4 levels in the blood rise; when T4 levels fall, the thyroid gland produces more T4, thereby continuously and closely regulating T4 levels in the body. Many middle-aged cats, however, develop a benign (non-cancerous) tumor in the thyroid gland. The cells that make up this tumor still produce T4, but their control mechanism is faulty. The normal feedback system that maintains a balanced T4 level in the body has no effect on these tumor cells, so that they continue to pump out T4 despite signals to stop. Cats with these tumors have their “go” switch permanently stuck in the “faster” position. This illness is termed hyperthyroidism. Typically, hyperthyroidism affects cats about ten to twelve years of age—the cat will become more active, but with a nervous energy that masks the true illness they are feeling. Vomiting, weight loss, and increased thirst are common symptoms of this disease, but they often come on so gradually that the problem is not easily noticed. In advanced cases, hyperthyroidism can lead to heart failure, kidney failure, and fatal blood clots. Hyperthyroidism can be readily detected with a standard blood test performed as part of your cat’s routine wellness plan. Today’s effective treatment options can actually cure the disease by killing off the abnormal tumor cells while leaving the normal thyroid cells undamaged, resulting in a normal life span for many affected cats.

Polycystic Kidney Disease

Polycystic kidney disease (PKD) is caused by a defective gene. The disease was first recognized in Persians, and is seen occasionally in other breeds, including Himalayans. Affected kittens are born with miniscule cysts inside the kidneys and sometimes the liver that slowly enlarge over time, eventually destroying the affected organ. Symptoms usually become apparent around seven years of age on average. These symptoms include weight loss, vomiting, excessive thirst, and poor overall health. There is no cure for PKD, although special diets and medication can slow the progress of the resulting organ failure; diagnosing PKD as early as possible may allow effective support of kidney and liver function for years. Routine annual urine or blood testing is therefore recommended to monitor for early organ dysfunction in all adult cats. If PKD is indicated, an ultrasound exam of the abdomen may be performed to visualize the cysts and assess the current damage. A genetic test for PKD is also available, and responsible breeders recommend that cats who carry the PKD gene should not be used for breeding.

Feline Asthma

Asthma, which causes inflammation and narrowing of the small airways of the lungs, is fairly common in cats. Certain cat breeds, including your Himalayan, are especially at risk. Asthma is a life-threatening condition that can require emergency treatment. Cats with asthma often have a wheezing cough; some owners may describe it as a “hairball cough,” but really when cats have a hairball, they typically don’t cough, they vomit. Coughing is much more likely to be a serious problem in a cat than in a human or a dog, for example, and any cough that lasts longer than a day or recurs over time should be checked out. Cats with asthma can be treated with inhalers as well as oral medications that help open the airways and reduce inflammation. Prompt treatment is needed for wheezing, gasping, coughing or any sign of respiratory distress in your cat.

Taking Care of Your Himalayan at Home

Much of what you can do at home to keep your cat happy and healthy is common sense, just like it is for people. Watch her diet, make sure she gets plenty of exercise, regularly brush her teeth and coat, and call us or a pet emergency hospital when something seems unusual (see “What to Watch For” below). Be sure to adhere to the schedule of examinations and vaccinations that we recommend for your pet. During your cat’s exams, we’ll perform her necessary “check-ups” and test for diseases and conditions that are common in Himalayans. Another very important step in caring for your pet is signing her up for pet health insurance. There will certainly be medical tests and procedures she will need throughout her life and pet health insurance will help you cover those costs.

Routine Care, Diet, and Exercise

Build your pet’s routine care into your schedule to help your Himmy live longer, stay healthier, and be happier during her lifetime. We cannot overemphasize the importance of a proper diet and exercise routine for your pet.

  • Supervise your pet as you would a young child. Keep doors closed, pick up after yourself, and block off rooms as necessary. This will help keep her out of trouble, off of inappropriate surfaces for jumping, and away from objects she shouldn’t put in her mouth.
  • She has long hair that will need brushing daily.
  • Himalayans have generally good teeth, and you can keep them perfect by brushing them at least twice a week!
  • Check her ears weekly for wax, debris, or signs of infection and clean when necessary. Don’t worry—we’ll show you how!
  • She needs daily play sessions that stimulate her natural desire to hunt and explore. Keep her mind and body active or she may develop behavior issues.
  • Cats are meticulously clean and demand a clean litter box. Be sure to provide at least one box for each cat and scoop waste daily.
  • It is important that your cat drinks adequate amounts of water. If she won’t drink water from her bowl try adding ice cubes or a flowing fountain.
  • Feed a high-quality feline diet appropriate for her age.
  • Exercise your cat regularly by engaging her with high-activity toys.

What to Watch For

An abnormal symptom in your pet could be just a minor or temporary issue, but it could also be the sign of serious illness or disease. Knowing when to seek veterinary help, and how urgently, is essential to taking care of your cat. Many diseases can cause cats to have a characteristic combination of symptoms, which together can be a clear signal that your Himalayan needs help.
