Disease

For several days, your cat has been acting uncharacteristically lethargic and off his food. Then one evening, while stroking his back, you feel a smallish lump just to the side of his tail. Although you touch the lump gently, he responds with a hiss, leaping from your lap and scurrying into a dark corner. The lump you discovered is quite possibly an abscess, and the sensitive swelling may indicate that the cat has an infection - and necessitating prompt veterinary care. Distinctive Characteristics. An abscess is a localized collection of pus, a yellowish fluid that forms at the site of an infection. Although pus typically contains a certain amount of cellular debris and dead tissue, it is composed mainly of white blood cells that have been summoned by the immune system to combat invading bacteria or other microorganisms. Cats can develop a variety of lumps and bumps on their skin - cysts, tumors, pimples and so forth - but abscesses have their own distinctive characteristics, notes William Miller, VMD, medical director at Cornell Universitys Companion Animal Hospital. "Because an abscess is filled with pus," he says, "it will be inflamed, warm and tender. Tumors are not usually like that, and pimples are merely superficial eruptions, affecting the outer layer of skin and minuscule by comparison to an abscess." External and Internal. An abscess may develop at the site of a penetrating wound - if a cat steps on a thorn, a wood sliver or a piece of glass, for example. But abscess-producing infections in cats usually result from bites from other cats, since the bacteria that cause infection are normal inhabitants of the feline mouth.

If your cat kept a diary, it might read something like this: Yesterday, I slept, ate, slept some more, chased a paper ball, napped, ate again and napped. While that may describe a cats typical day, it wont necessarily help you or your veterinarian if your cat develops a health or behavior problem. "Keeping a diary for your cat is a good idea in general, but particularly when your cat is ill," says Drew Weigner, DVM, who is board-certified by the American Board of Veterinary Practitioners. Keep Track of the Basics. At a minimum, you should track your cats veterinary visits, vaccinations, flea treatments and any medications your cat takes. Beyond that, record anything that is unusual for your particular pet. For example, if you change your cats diet, note the date and track changes (such as vomiting or diarrhea). Or, if your cat urinates more or less often than usual, record that in the diary. "If there is anything unusual, or if you start seeing something more often, you should take a trip to the veterinarian," says Dr. Weigner, whose practice is The Cat Doctor in Atlanta, Georgia. If your cat exhibits any changes in behavior, you should note anything unusual thats happened in the house, such as human visitors or changes in the environment. Are strange cats hanging around outside? "Anything can act as a trigger," says Dr. Weigner. "Keeping a journal helps separate the subjective from whats objective. If you keep a log of it, you know for sure."

Although one cat may be prettier, smarter or more athletic than another, nature plays no favorites when it comes to doling out heart disease. All cats are at potential risk for serious insult to this vital organ. In some cases, the signs are obvious to the trained eye. In others, a serious heart disorder can remain hidden for years before finally expressing itself in a sudden, perhaps fatal, deterioration of function. The best thing that owners can do is to make sure their cats have thorough medical checkups - at least once a year - during which the veterinarian pays close attention to the heart. While examination with a stethoscope cannot detect all feline heart diseases, its probably the most cost-effective approach to diagnosis in otherwise healthy cats. Congenital Defects. Most feline heart disorders are acquired during the course of an animals life, but others are present at birth. However, says John Bonagura, DVM, a professor of veterinary clinical sciences at the Ohio State University Veterinary Hospital, congenital feline cardiac disease is relatively rare, occurring only in an estimated one or two percent of kittens. The most common congenital disorders, he notes, are heart valve malformations and holes in the septa. Abnormal valve development most often involves the mitral valve, located between the left atrium and the left ventricle. While a number of structural problems can occur, the end result is typically a valve that cannot close properly and thus allows blood to leak backwards into the atrium. Holes in the septa most frequently affect the membrane partitioning the right and left ventricles and may also cause the inappropriate flow of blood between the heart chambers.

A wide variety of irritants — from minor and transient to severe and indicative of a major health problem — can affect any portion of the feline respiratory system, whose purpose is to warm and humidify inhaled air, deliver oxygen to the lungs, and expel carbon dioxide and other waste gases. A complex pathway of tracts and organs, the upper respiratory system consists of the nose; two nasal passages; the nasal cavity (a hollow structure surrounded by air-filled spaces that are situated just above and below the eyes); and the pharynx (a cavity behind the mouth) that opens, via a passageway called the larynx; to a tubular structure, the trachea, a flexible tube commonly referred to as the windpipe.

Governor Linda Lingle, accompanied by State Civil Defense Director, Major General Robert Lee, highlighted the importance of emergency preparedness by showcasing Hawaiis ongoing emergency shelter programs for people with special health needs and pet-friendly shelters. State Civil Defense, working with the State Department of Education, county civil defense agencies, American Red Cross, Department of Health, Hawaiian Humane Society and other public and private sector partners, has designated 158 facilities statewide that may serve as Special Health Needs shelters, and another 55 facilities that may be used as Pet-Friendly shelters. These shelters are located in separate rooms or buildings on public school campuses where general population emergency shelters are also located.

Baycom Diagnostics, Inc. has developed a cost effective diagnostic kit for monitoring and testing feline and canine diabetes. Currently, veterinarians use hand held glucose meters to test cats and dogs for the potential of diabetes. These meters are a critical part of human diabetes management, yet often do not work well with small animals, are expensive and must be used several times a day. The companys president says veterinarians could administer Baycoms product in a simple, easy test once every 90 days to get an accurate measurement.

Digestive system disorders in general are among the most frequently observed health problems in cats. While many of these disorders are primarily associated with organs such as the liver, pancreas and gall bladder - all of which play a crucial role in the digestive process - plenty of them are centered in the alimentary canal, the long tube leading from a cats mouth to its anus. Most Common. By far the most prevalent feline digestive tract disorder, says Dr. Bartges, is inflammatory bowel disease (IBD). The condition, characteristically evidenced by chronic vomiting and diarrhea, is widely thought to be the consequence of several different disorders involving the feline immune system. The changes that are consistently found upon microscopic analysis in the lining (mucosa) of an affected cats intestines - a superabundance of immune system cells, for example - suggest that abnormal immune system activity may precipitate the disease.

ChemNutra Inc., a Las Vegas-based ingredients broker, pleaded guilty on June 16 to federal charges of distributing tainted wheat gluten that led to the mass pet food recalls of 2007. The charges stem from a February 2008 indictment that alleged ChemNutra imported more than 800 metric tons of melamine-contaminated wheat gluten from China between November 2006, and February 2007, then sold the product to various pet food manufacturers.

One mosquito bite can infect a cat with heartworm, a potentially destructive and insidious disease, which reveals itself as H.A.R.D. (Heartworm Associated Respiratory Disease). The American Heartworm Society (AHS) and the American Association of Feline Practitioners (AAFP) have teamed up to get this urgent message out to cat owners through the KNOW Heartworms campaign (www.knowheartworms.org). Experts now feel that heartworm prevention in cats is extremely important because the dangers of heartworm disease are much more significant that previously believed. Here are five common myths about heartworm disease that can put your pet at serious risk.

Your cat normally uses the litter box a few times a day to relieve herself, but today is different. Shes going to the box every few minutes and vocalizing as she strains to urinate. The small amount of urine that finally dribbles out is filled with blood. Your cat may be suffering from bladder stones, a painful condition that, left untreated, can lead to serious illness and in rare cases, death. Causes of Bladder Stones. Bladder stones, or uroliths, are caused by an extensive concentration of salts and minerals in the urine such as magnesium, phosphorous, calcium, and ammonia. "There should always be a certain amount of salts and minerals in the urine," says Richard Goldstein, DVM, an associate professor of small animal medicine at Cornell Universitys College of Veterinary Medicine. "But when the urine becomes super saturated - meaning theres an overabundance of salts and minerals - crystals begin to form."

Although the feline pancreas is a relatively small internal organ, typically weighing no more than six or eight ounces, it plays a demanding and multifaceted role in maintaining a cats robust health. Indeed, a disease or injury that results in the inflammation of this vital organ - a condition called pancreatitis - could prove fatal unless the animal receives prompt, and potentially quite expensive, medical care. The pancreas is a slender, pink, v-shaped strip of tissue resting snugly within the cats abdomen between its left kidney and its duodenum. It is a glandular organ that performs two life-sustaining functions-endocrine and exocrine. While still in the pancreas, explains Richard Goldstein, DVM, an associate professor of small animal medicine at Cornell Universitys College of Veterinary Medicine, these digestive enzymes are normally sequestered in tiny droplets that prevent their coming into direct contact with pancreatic tissue. Moreover, he says, the enzymes are biologically programmed to remain inactive until after they have been secreted and have traveled via the pancreatic duct into the small intestine.

Quite often, I am told tales of apparently mild-mannered cats that seem to tolerate all of lifes challenges save one: the Trespasser. When face to face with a Cat Errant, Mr. Mellow just cannot cope. We are all cat lovers and certainly wish no harm to our neighbors cats. But naturally, we want to look out for our family. When a resident cat spies a potential intruder, several responses are possible. If you are lucky, your cat might believe that the more, the merrier. He may chirp, he may posture in a beckoning manner, or he may continue to nap calmly, with no apparent interest in the antics of his comrade through the glass. If you are less lucky, you may find that your cat does not trust that the glass is sufficient to keep an offending cat at bay. He may post "Private Property" signs of his own. You may come home to discover that your windows and doors have been marked with urine. If you manage to get through the winter months unscathed, beware the ides of April. For when the windows are opened for a little fresh air, the urgency to reset the barriers will return. The most concerning cat of all is the cat that experiences profound fear upon viewing an unfamiliar cat. The frightened cat may respond by redirecting aggression toward a member of your household. Although other cats are most frequently targeted, other pets and people may find themselves victims of serious attacks. The impact on a relationship can be devastating. Fortunately, you can intervene. You will need to work with both sides of the equation.
