Welcome to Weymouth Landing Cat Clinic's Newsletter

Kittens have 26 temporary teeth that begin to erupt at about two to three weeks of age. They have 30 permanent teeth that emerge at about three to four months.

Studies show that 70 percent of cats show signs of gum disease by age three. Symptoms include yellow and brown build-up of tartar along the gumline, red inflamed gums and persistent bad breath.

Feline Odontoclastic Lesions (FORL), commonly called cervical line lesions, are the most common dental disease of domestic cats. The disease was virtually unrecognized until the mid-1970's. Recent studies show about 28 percent of domestic cats show at least one lesion. The lesions often begin below the gumline, so they can develop undetected. Often, the first sign to the pet owner is a severely inflamed gum around a tooth. Cat owners should seek veterinary care if their cat exhibits pain or inflammation around the gums.

Hepatic lipidosis, also known as fatty liver syndrome, is a common and very serious condition that occurs in fat cats who, for some reason or another, have stopped eating. The disease results from an accumulation of fat in the liver and, if not treated during the early stages, can be deadly. Hepatic lipidosis is treatable and cure rates are good if the cat is presented to a veterinarian during the early stages of the disease.

Why would a fat cat not be eating?

Here are some reasons:

• Bad teeth
• Intestinal blockage
• Stress - examples: Moving into a new home, introducing a new animal into the family, owner goes on vacation
• Hairball
• Illnesses

These are all good reasons why a cat would stop eating. The most common reason for a cat to stop eating is an upper respiratory infection.

Think about it - cats like their food because they enjoy it and are familiar with the smell. So if a cat can't smell its food, it's not going to eat.

The question is: "What would cause a cat to loose its ability to smell food?"

An upper respiratory infection could cause a cat to loose its sense of smell.

Cats get upper respiratory infections all the time - sneezing, runny nose, runny eyes.

So, you have a fat cat that gets the flu and can't smell. Since the cat cannot smell his food, he stops eating. The body is looking for ways to feed itself, and tries to do this by converting stored fat into energy. In order for the fat to be converted into fuel, it must pass through the cat's liver. The liver can't handle this fatty saturation and liver dysfunction ensues. This doesn't happen to thin cats. They don't have enough fat available to mobilize and create this problem.

Many owners do notice that their cat is not eating, but they think, "That's all right, Tiger needs to lose a few pounds." Then, after a week or two without an appetite, they start to worry and finally bring the animal to the veterinarian. If they don't bring their cat in soon enough, he (or she) is a prime candidate for hepatic lipidosis.

Symptoms associated with hepatic lipidosis include loss of appetite, vomiting, depression, weight loss and lethargy. Some cats develop a yellow coloration of the eyes, ears and mouth. This yellow coloration (particularly of the mucus membranes) is jaundice and usually indicates liver disease and/or red blood cell destruction.

The prognosis for cats with hepatic lipidosis is good if treatment is not delayed. The longer that treatment is delayed, the less likely for recovery. Cats that have underlying diseases (cancer, pancreatitis) are less likely to recover.

How would a veterinarian treat a cat with hepatic lipidosis? The veterinarian would probably hospitalize the cat, and among other treatments, feed it through a tube. After your cat has recovered from hepatic lipidosis, or, before your fat cat gets hepatic lipidosis, you should put your cat on a veterinarian-recommended low-calorie diet. Exercise is an important factor in weight loss, so it is important to encourage exercise via catnip or toys. Carefully monitoring your cat's food intake in times of stress (for example, the addition of a new pet) can be crucial in preventing mortality due to hepatic lipidosis.

Preventing obesity is the best way to prevent hepatic lipidosis. Regular meals should be given and free-choice feeding should be avoided. Obese cats should be placed on a special diet food. By slimming Tiger down, you could save him from hepatic lipidosis and other life-threatening diseases related to cat obesity.

Diabetes is a condition caused by a relative resistance to or deficiency of insulin which results in elevated blood glucose levels and glucose in the urine. Diabetes mellitus is most common in older cats; however, neutered cats, male cats and obese cats are at an increased risk of developing this condition. Evidence has shown that genetics may play a role in the development of diabetes in cats. In particular, the Burmese breed has been identified as being predisposed to diabetes, and analysis of pedigrees has suggested that this is an inherited trait.

Insulin is produced by the pancreas and is released into the bloodstream where it travels to all the tissues of the body. Its main role is to enable cells to take up glucose (sugar) which is needed as an energy source.

In diabetic cats, there is a relative or absolute deficiency of insulin. An absolute insulin deficiency may arise as a direct failure of the pancreas to produce insulin. In most diabetic cats, there is both an absolute insulin deficiency and a situation whereby cells of the body fail to respond effectively to the insulin produced. This results in a decreased amount of glucose taken up by the cells and an increase of glucose in the blood (called hyperglycemia). As the cells are starved of glucose, the body begins to break down stored fats and proteins for sources of energy. This process results in weight loss and the accumulation of toxic waste products, which can cause a diabetic crisis known as ketoacidosis.

The symptoms of diabetes may be severe or mild. Due to the increased amount of glucose in the blood, it is excreted in the urine. The glucose that is passed into the urine takes water with it, so an increased volume of urine is produced. To compensate for the water lost to the urine, the cat develops an increased thirst. Weight loss and an increased appetite are also frequently seen.

Usually the client brings the cat to see a veterinarian as a result of the following symptoms:
Weight loss
Increased appetite
Increased urination
Increased water consumption

These signs are not always present or may pass unnoticed. If a cat spends most of his time outdoors, the increased thirst and increased urination may not be noticed by the owner.

There are other clinical signs that may be observed. These include:

• Straining to pass urine or passing bloody urine (associated with a urinary tract infection)
• Poor coat
• Cataracts and retinal abnormalities causing vision problems
• Weakness in hind legs or dropped hocks

Some cats develop ketoacidosis, a potential complication in uncontrolled diabetes. In this situation, the cat may become extremely depressed, with symptoms such as vomiting, diarrhea, complete loss of appetite, dehydration, collapse and coma. If any of these signs are seen in a diabetic cat, it is an emergency condition and should be taken to a veterinary hospital immediately.

Blood and urine tests are required to confirm a diagnosis of diabetes. The diabetic cat needs to be hospitalized and monitored very closely. The treatment regime is initiated and necessary changes are made. This initial stabilization period usually takes between a few days to a couple of weeks. Some cats will need to be stabilized in-hospital initially, while others can be started as out patients. During this period, several parameters are monitored. Some of these parameters include:

• Weight
• Appetite
• Personality
• Thirst
• Urine Analysis
• Blood glucose measurements

Diabetes mellitus is usually a treatable condition, but requires considerable dedication and commitment from the cat’s owners. Owners of a diabetic cat need to be aware that a strict routine must be followed. The timing of insulin injections is important; however, they initially can be altered to suit the lifestyle of the owner. Once the insulin injections have begun, they need to be given at regular intervals. Knowledge on correct insulin storage, handling and administration is also required. The dose of insulin given should never be changed without consulting your veterinarian. One of the most common reasons for poor stabilization at home is problems with insulin storage and/or administration.

The most life-threatening complication that can occur at home is hypoglycemia (low blood glucose levels). Hypoglycemia can occur if an insulin overdose is given or if the cat has no appetite. The main signs of hypoglycemia are (in order of increasing severity):

• Weakness
• Disorientation
• Staggering
• Strange behavior—aimless wandering, searching for food, licking lips
• Severe neurological signs—collapse, convulsions, loss of consciousness

Ketoacidosis is an uncommon complication of poorly controlled diabetes. It can be rapidly fatal if not treated and is cause for immediate concern. The clinical signs most frequently seen with ketoacidosis are:

• Loss of appetite
• Weakness
• Vomiting/diarrhea
• Dehydration
• Collapse

Initially, all diabetic cats should be seen every one to two weeks in order to assess how well their diabetes is being controlled. It is not uncommon for problems to be seen in the early stages of care. Problems are often related to the storage and administration of insulin; therefore, they are usually quite easy to identify and remedy.

The long-term outlook for cats with diabetes mellitus varies according to how old they are, the ease of stabilizing their diabetes, and whether or not they have any other concurrent disease. Many diabetic cats have an excellent quality of life and can live for many years.

Thanks to the creation and marketing of cat litter in the mid 1940's, more and more cats have become indoor-only pets. As such, cats are now leading longer lives, with some living 20+ years! Our homes offer a safer, healthier environment than life on the street. The average life span of an indoor cat is 10 years, whereas the average lifespan of an outdoor cat is just 2 years. There is no doubt that indoors is safer.

Yet, when we choose to make our cats indoors-only companions, we have a responsibility to provide the stimulation that was previously provided by the great outdoors. Scratching and climbing posts become trees; interactive toys become hunted birds, bugs and field mice. A rotating array of cat playthings provides excitement, unpredictability and exercise which, in turn, gives your cat everything it needs while extending its life inside. With that said, many cat lovers still prefer to commune with nature with their feline friends. Fortunately, there are several ways to minimize the risks.

Most importantly, while vaccinations are important for indoor cats, they are absolutely critical to the health of outdoor cats. The threat of rabies, FeLV, FIV, and FIP, transmitted through altercations with wildlife, or interaction with stray, un-vaccinated cats, should be enough to have your cat immunized in order to give you peace of mind. All of these diseases can be prevented and can provide your outdoor cat with proper protection should he need it.

If you feel as though your cat deserves the fun of being outside, but want to provide a safe way to experience nature, there are alternatives to opening the door and watching him go. Harnesses and leashes (gasp!) have been developed for cats. Either cat specific or small dog accessories fit well and are relatively inexpensive. Training your cat to walk with the harness takes patience (unless you start with a kitten, in which case it could take less time), but the reward is worth it. Your cat will be able to experience the joys of being outside in a controlled environment. How far he can travel is up to you!

Outdoor enclosures are another great alternative. Since outdoor enclosures are usually homemade, they come in all shapes and sizes. For durability, chicken wire or wire hardware cloth - secured around a simple wood frame - is preferable to ordinary window screening. The most successful structures usually feature climbing and resting furniture inside. A shaded area is necessary for warm or hot weather. Whether you choose an outdoor enclosure or add cat-proof netting to the top of traditional fencing, they are safest used only when you are at home able to check on them often.

Even with the option of training or providing your cat with an enclosed outdoor adventure area, you still need to consider identification. Lost cats result in heartache that can easily be avoided. Microchip and ID tags provide easy identification and may be what reunites you with your cat should he / she get lost or scooped up by a caring, but ignorant stranger.

When deciding whether or not to let your cat outdoors, it is important for you to consider the alternatives. As the pet industry expands and becomes more creative, more and more indoor/outdoor products are going to become available. Of course, there is nothing better than being outside. If you can provide your cat with the proper care and protection, allowing your cat to go outdoors can be a fun and healthy existence.

There is almost nothing more comforting than when a cat jumps on our lap and begins to purr. Ever since the Egyptians started worshiping the cat, philosophers, scientists and cat lovers worldwide have wondered why cats purr. When we hear and feel this purring, we assume that everything is just fine with the cat. But why do cats purr? And what produces this sound?

Purring is a mystery. No one can definitively say which mechanism in a cat creates the purr. Some feline experts believe purring is due to a vibrations caused by blood passing through a large vein in the cat's chest. Yet others who have studied purring think it's due to the vibration of the vocal cords when the animal inhales and exhales.

It appears as though purring is not just limited to domestic cats. Some wild cats, such as pumas and mountain lions, are able to purr. In general, most large cats that cannot roar are able to purr. The calls of the leopard vary and include a series of harsh coughs, throaty growls, and deep, purring sounds.

It turns out that cats have special wiring traveling from the brain to the muscles in the vocal cords. Nerve signals that pass through this wiring system cause vibrations of the vocal cords. While the nerves cause the vocal cords to vibrate, the air forced through them by the diaphragm causes the musical hum. Since breathing has both inspiratory and expiratory phases, cats can purr continuously. The problem with this theory, however, is that cats continue to purr even when the nerves to the area of the vocal cords have been injured or damaged.

It is commonly believed that cats purr when content. However, cats also purr when they are severely injured, frightened or giving birth. According to some veterinarians, the original function of the purr was to enable a kitten to communicate with his mother that things are going well. A kitten is able to purr by the second day of life, and although he can't meow and nurse at the same time, he can purr and nurse.

As the cat matures, the meaning of the purr changes. Some cats purr to indicate contentment or pleasure, but badly frightened cats and severely ill cats also purr. It is not uncommon for cats to purr when they are close to death. This final purring may indicate a state of anxiety or possibly euphoria. These states have also been elucidated in terminally ill people.

Since the purr has lasted through hundreds of generations of cats, there must be a survival mechanism behind its continued existence. Researchers believe that self-healing is the survival mechanism behind the purr. There is extensive documentation that suggests that low frequencies, at low intensity, are therapeutic. These frequencies can aid bone growth, fracture healing, pain relief, tendon and muscle strength and repair, joint mobility, the reduction of swelling, and the relief of dyspnea, or breathlessness.

Animal behaviorists believe that when cats purr under stressful circumstances, they are reassuring or comforting themselves, much as humans may sing to themselves or hum when they are nervous. Frightened cats may purr to communicate submissiveness or non-aggressive intentions. A feral cat may purr to signal that he is not planning to attack and other cats need not feel threatened. Older cats may purr when they play or approach other cats, signaling that they are friendly and want to come closer.
