Birmans, or "Mitted Cats"

Your cat is special! She senses your moods, is curious about your day, and has purred her way into your heart. Chances are that you chose her because you like Birmans and you expected her to have certain traits that would fit your lifestyle, like:

• Might "chirrup" or trill her meows to call you when she misses you
• An affectionate companion and family cat
• Good with children and other pets
• Requires minimal grooming
• Excellent companion

For her best health, pay attention to these traits:

• Needs regular exercise and diet regulation to avoid weight gain
• Needs the company of other pets or people and does not do well in isolation
• Exhibits signs of separation anxiety if left alone too much

Is it all worth it? Of course! She's full of personality, and you love her for it! She is gentle, friendly and loves to be involved in your daily activities.

The origin of the Birman remains a mystery with many unverified tales of their beginnings. Born all white, Birmans do not develop their full color until maturity. They keep their unique white “mittens” on all four paws. Birmans are very social and happy to be involved in your daily activities. They are less apt to climb and jump onto high places, preferring to hang out at ground level or on the couch. Birmans have a playful side and will play fetch or chase when engaged, but prefer to lounge with their family.

Your Birman's Health

We know that because you care so much about your cat, you want to take great care of her. That is why we have summarized the health concerns we will be discussing with you over the life of your Birman. By knowing about the health concerns common among Birmans, we can help you tailor an individual preventive health plan and hopefully prevent some predictable risks in your pet.

Many diseases and health conditions are genetic, meaning they are related to your pet’s breed. The conditions we will describe here have a significant rate of incidence or a strong impact upon this breed particularly, according to a general consensus among feline genetic researchers and veterinary practitioners. This does not mean your cat will have these problems, only that she may be more at risk than other cats. We will describe the most common issues seen in Birmans to give you an idea of what may come up in her future. Of course, we can’t cover every possibility here, so always check with us if you notice any unusual signs or symptoms.

This guide contains general health information important to all felines as well as information on genetic predispositions for Birmans. The information here can help you and your pet’s healthcare team plan for your pet’s unique medical needs together. At the end of the article, we have also included a description of what you can do at home to keep your Mitted Cat looking and feeling her best. We hope this information will help you know what to watch for, and we will all feel better knowing that we’re taking the best possible care of your friend.

General Health Information for your Birman

Weight Management

Obesity is a major disease that contributes to a surprisingly large number of illnesses and deaths in cats.

This revelation is more well-known and well-understood today than in the last few decades, but too many owners are still ignoring the dangers of extra weight on their pets. Excess weight is one of the most influential factors in the development of arthritis, diabetes, and other life-threatening diseases. Everyone knows—many firsthand from personal experience—how even shedding just a few pounds can result in improved mobility and increased overall motivation to be active. And the same is true for your pet.

Research suggests that carrying excess weight may shorten a pet’s life by as much as two years, and can cause the onset of arthritis two years sooner. Diabetes, an inherited disease, has a much higher chance of developing in overweight pets, and may never become a problem for a healthy-weight cat. The more obese a cat becomes, the more likely it will become diabetic. Hepatic lipidosis, or fatty liver, is another potentially fatal disease in overweight pets; hepatic lipidosis can develop in as few as 48 hours when an overweight cat stops eating for any reason.

So how can we help our pets stay trim? Understanding your cat's dietary habits is key. The average cat prefers to eat about 10-15 times a day, just a few nibbles at a time. This method, free-feeding, works well for most cats, but boredom may increase the number of trips your cat makes to the food bowl. By keeping your cat playfully active and engaged, you'll help your pet stay healthy and have some fun at the same time! A string tied to a stick with something crinkly or fuzzy on the other end of the string, and a little imagination—you and your cat will both be entertained. Food puzzles, like kibbles put in a paper bag or under an overturned basket or box, may help to motivate cats with more food-based interests to romp and tumble.

For really tough cases of overeating, you will have to take a firm stance, and regulate your cat’s food intake. Instead of filling your cat’s bowl to the top, follow the feeding guide on the food package and be sure to feed a high-quality adult cat diet as recommended by your vet. Replace your cat's habits of eating when bored with extra playtime and affection. Cats typically adjust their desires for personal interaction by the amount of affection offered to them, so in other words, ignoring your cat means your cat will ignore you. By the same token, loving on and playing with your cat a lot will cause your cat to desire that time with you. A more active cat means a healthier, happier pet—and owner!

Dental Disease

Dental disease is one of the most common chronic problems in pets who don’t have their teeth brushed regularly. Unfortunately, most cats don’t take very good care of their own teeth, and this probably includes your Birman. Without extra help and care from you, your cat is likely to develop potentially serious dental problems. Dental disease starts with food residue, which hardens into tartar that builds up on the visible parts of the teeth, and eventually leads to infection of the gums and tooth roots. Protecting your cat against dental disease from the start by removing food residue regularly may help prevent or delay the need for advanced treatment of dental disease. This treatment can be stressful for your cat and expensive for you, so preventive care is beneficial all around. In severe cases of chronic dental infection, your pet may even lose teeth or sustain damage to internal organs. And, if nothing else, your cat will be a more pleasant companion not knocking everyone over with stinky cat breath! We’ll show you how to keep your cat's pearly whites clean at home, and help you schedule regular routine dental exams.

Vaccine-Preventable Infections

Like all cats, Birmans are susceptible to bacterial and viral infections such as panleukopenia, calicivirus, rhinotracheitis, and rabies, which are preventable through vaccination. The risk of your cat contracting these diseases is high, so the corresponding vaccines are called “core” vaccines, which are highly recommended for all cats. In addition, vaccines are available to offer protection from other dangerous diseases like feline leukemia virus (FeLV). In making vaccination recommendations for your cat, we will consider the prevalence of these diseases in our area, your cat’s age, and any other risk factors specific to her lifestyle.

Parasites

All kinds of worms and bugs can invade your Mitted Cat's body, inside and out. Everything from fleas and ticks to ear mites can infest her skin and ears. Hookworms, roundworms, heartworms, and whipworms can get into her system in a number of ways: drinking unclean water, walking on contaminated soil, or being bitten by an infected mosquito. Some of these parasites can be transmitted to you or a family member and are a serious concern for everyone. For your feline friend, these parasites can cause pain, discomfort, and even death, so it’s important that we test for them on a regular basis. Many types of parasites can be detected with a fecal exam, so it’s a good idea to bring a fresh stool sample (in a stink-proof container, please) with your pet for her twice-a-year wellness exams. We’ll also recommend preventive medication as necessary to keep her healthy.

Spay or Neuter

One of the best things you can do for your Birman is to have her spayed (neutered for males). In females, this procedure includes surgically removing the ovaries and usually the uterus; in males, the testicles are surgically removed. Spaying or neutering your pet decreases the likelihood of certain types of cancers and eliminates the possibility of your pet becoming pregnant or fathering unwanted litters. Both sexes usually become less territorial and less likely to roam, and neutering particularly decreases the occurrence of urine spraying and marking behaviors in males. Performing this surgery also gives us a chance, while your pet is under anesthesia, to identify and address some of the diseases your cat is likely to develop. For example, if your pet needs hip X-rays to check for dysplasia or a thorough dental exam to look for stomatitis, these procedures can be conveniently performed at the same time as the spay or neuter to minimize the stress on your cat. Routine blood testing prior to surgery also helps us to identify and take precautions against common problems that increase anesthetic or surgical risk. It sounds like a lot to keep in mind, but don’t worry - we’ll discuss all the specific problems we will look for with you when the time arrives.

Genetic Predispositions for Birmans

Arterial Thromboembolism

Cats with heart disease may develop blood clots in their arteries known as FATE (feline aortic thromboembolisms). Blood clots most commonly become lodged just past the aorta, the large blood vessel that supplies blood from the heart to the body, blocking normal blood flow to the hind legs. When this happens, one or both hind legs may become paralyzed, cold, or painful. FATE is a life-threatening disease, and requires quick action and prolonged medical care. Cats who survive thromboembolisms, however, usually regain full function of their limbs. If your cat is diagnosed with heart disease, we may prescribe medications to help lower the risk of blood clots. If your cat suddenly can’t walk or is dragging one or both back legs and crying, don’t wait! Your pet needs immediate emergency care.

Hemophilia

The term hemophilia refers to a group of blood clotting disorders in which wounds in the body bleed continuously and profusely. Several types of these inherited blood disorders can occur in cats and range from mild to severe effects. Even with mild cases, however, hemophilia disorders can be life-threatening. A cat affected by hemophilia may seem completely normal until an injury occurs or surgery is performed, after which dangerous, prolonged bleeding may begin. For at-risk breeds like your Birman, diagnostic testing to detect abnormal clotting times is recommended before any type of surgery or dental extraction.

Blood Type

Although we hate to think of the worst happening to our pets, when disaster strikes, it’s best to be prepared. One of the most effective life-saving treatments available in emergency med

Just like people, individual cats have different blood types. Most domestic cats have type A blood, but purebred cats, like your Birman 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 Birman. If you plan to breed your cat, you will need to learn more about this problem beforehand from your veterinarian.

Neutrophil Granulation

Neutrophils are a type of white blood cell present in normal blood that we expect to see (under the microscope) in certain quantities and conditions as part of routine blood testing. The number and appearance of neutrophils and other white blood cells can give us clues about your cat’s health. Usually granules present in these neutrophils would be a cause for alarm and indicative of infection or illness, but with your Birman, these granules may be perfectly normal. These unusual cells are not a problem, and are not associated with any disease, but we need to keep this normal biologic variation in mind when interpreting your cat's special lab results.

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.

FIP Susceptibility

Feline Infectious Peritonitis, or FIP, is a fatal disease caused by a type of coronavirus. All cats may carry this virus in a dormant state, but if the virus undergoes a combination of specific mutations, it can act on a susceptible cat’s immune system, causing the cat to develop FIP. Birmans seem to be more at risk for developing FIP than other breeds. FIP causes damage to the blood vessels (vasculitis) and fluid build-up inside the abdomen or chest. Blood testing is available for detecting coronaviruses in cats, but these tests don’t differentiate well between non-harmful coronaviruses and the actual FIP disease. Screening cats for this disease before breeding or selling them is therefore difficult and unreliable. FIP is always a risk for any kitten, but more so when purchasing a purebred cat from a breeder; once FIP has developed in a cattery population, it is tough to get rid of it. Be very careful to ask about any history of FIP infection in a kitten or cat's family or cattery history before purchasing your pet. Unfortunately, there is currently no effective treatment for FIP, and it is a fatal disease.

Multiple Eye Problems

Not many things have the dramatic impact on your cat's quality of life as the proper functioning of his eyes. Unfortunately, Birmans can inherit or develop a number of different eye conditions, some of which may cause blindness if not treated right away, and most can be extremely painful! We will evaluate your cat's eyes during every visit to look for any troublesome signs.

Cataract

Cataracts are a common cause of blindness in older Birmans. Onset of the disease presents with the lenses of the eyes becoming more opaque, or more cloudy than clear. Surgery to remove cataracts and restore the cat's sight may be an option, although most cats adjust well to gradually losing their vision and still get along well in life. The Point Vicente Animal Hospital team will always examine your cat's eyes closely at each biannual exam and will discuss treatment options with you if your cat develops cataracts.

Eyelid Agenesis

Eyelid agenesis is a birth defect in which the upper eyelid does not form properly. This malformation leaves the eye constantly vulnerable to foreign materials contacting the cornea, like dust, eyelashes, and hair. In addition, the eye is never properly hydrated, and remains irritated, red, and dry as a result. Over time, this irritation causes painful corneal ulcers and scar tissue to develop, eventually leading to partial or complete blindness. In mild cases, treatment may include the application of eye lubricant and cryosurgery to remove the eyelashes rubbing the eye. Usually though, affected cats are treated through surgical eyelid reconstruction. Once healed, the new eyelids should function normally, and the cat should be able to live a healthy life with normal vision.

Corneal Sequestration

Corneal sequestration is a painful condition common in breeds with prominent eyes, like Birmans. A corneal sequestrum is a hard black patch of dead tissue that develops on the front of the cat’s eye, or the cornea. This condition usually develops as the result of chronic inflammation due to viral infection, eyelid defects, or even eyelashes that grow the wrong way. Some early cases may be managed fairly well for months to years using topical medications, but in more advanced cases, preventive surgery may be able to repair the defect and save the eye before the sequestrum detaches. So keep an eye out for any signs of eye infection in your cat, and we’ll check for this condition and other potential eye problems at each semi-annual wellness exam too.

Hypotrichosis

Hypotrichosis is caused by a recessive genetic defect found in several cat breeds, including Birmans. This disease causes thinning of the hair or balding, which tends to develop in patterns or patches on the torso and head. A kitten can be born with symmetrical hair loss, or thinning of hair may ensue shortly after birth. In time, affected areas may develop additional pigmentation or thickened skin. Skin biopsy samples will indicate if your cat has a lower-than-normal number of hair follicles, sebaceous glands, or sweat glands. Hypotrichosis is not painful, but special care is required to protect your cat's skin. No effective treatment is currently known for this condition. Because it is genetically linked, affected cats and their close relatives should not be bred.

Taking Care of Your Birman 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 Birmans. 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 Mitted Cat 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.
• Despite her long hair she sheds little, and requires brushing only once or twice a week.
• Birmans 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 Birman needs help.
