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.

What once was termed "renal failure" is now called feline chronic kidney disease (CKD), in part because the word "failure" sounded too terminal: Many cats live on for years (with treatment) with chronic kidney disease. One such survivor was the first ShortTakes office manager, the late, great Gertie. That stalwart kitty was diagnosed with renal failure in "middle age," around 11 years old. She hung on to see her 20th birthday - a little shaky toward the end - but mostly thriving with good "quality of life" thanks to expert veterinary care, therapeutic renal diets, blood pressure medicine for her hypertension, and plenty of fresh water for the thirst that goes along with kidney disease.

Despite its typical durability, a cats skin is subject to a wide array of disorders. Most of these conditions, in themselves, are of minor consequence and readily treatable. But all of them merit examination by a veterinarian, since they can signal the presence of a serious infection or other potentially life threatening systemic health problem. Among the various feline skin conditions that might be overlooked - or ignored - by an owner is acne. This disorder, characterized by the emergence of tiny black eruptions (blackheads) on a cats chin and lips, is a condition that can afflict both male and female cats of all ages and breeds. The presence of blackheads usually amounts to nothing more than a cosmetic problem, says William H. Miller, Jr., VMD, a professor of dermatology and medical director of the Companion Animal Hospital at Cornell Universitys College of Veterinary Medicine. However, he points out, feline acne - which appears only on an affected cats face - can evolve into a serious health issue if the benign blackheads turn into pus-filled boils (furuncles) that may signal the presence of a deep-seated bacterial or fungal infection.

During the past half-century, no fewer than 10 vaccines have been developed that, according to their manufacturers, can protect your cat against a wide variety of lethal feline diseases. In general, these claims of efficacy have been justified. According to Fred Scott, DVM, PhD, professor emeritus of virology at Cornell Universitys College of Veterinary Medicine and the founding director of the Cornell Feline Health Center, the vaccines have been responsible for "a tremendous improvement in feline health." He cites as a prime example the vaccine created to protect against the feline panleukopenia virus (FPV). "Prior to the late 1960s and early 1970s," says Dr. Scott, "half of all cats that passed through a shelter developed panleukopenia within a few days - and as many as 90 percent of them died from it. Today, the FPV vaccine has totally controlled the disease in properly vaccinated cats. The only time you see it now is in unvaccinated feral or farm cats or those that are in shelters, but that is rare." However, he points out, there are several reasons why owners should refrain from having their cats inoculated annually with every available vaccine. For example, it is remotely possible for a vaccine to damage a developing fetus or stimulate an allergic reaction. And of growing concern is the development of vaccine-associated sarcoma - a type of cancer that, for unknown reasons, emerges at the site on a cats body where a vaccine has been injected. Furthermore, research has brought into question the need for all cats to be routinely revaccinated with all available vaccines every year throughout their lives. Certain laboratory tests may reveal that, as the result of a previous vaccination or natural exposure to an infectious agent, the antibody levels in a cats blood remain high enough to protect it against a specific virus or bacterium. In that case, the animal would be protected against disease associated with that infectious agent and a booster shot would be unnecessary.
