Disease

Of all the animals in shelters, young kittens are usually the most at risk. Theyre fragile, prone to infectious illnesses and have special care needs. While some are placed in foster homes to be hand-raised until they are old enough for adoption, many shelters euthanize them as soon as they are brought in because they dont have the infrastructure or staff to care for them.

Demystifying the ingredients in commercial food is only one step in providing a healthy diet for our cats. The ongoing challenge is preventing the spread of food-borne illness to animals and people in the household. At last count, manufacturers had recalled five of six dog and cat foods this year because of possible contamination with the bacteria salmonella. The sixth recalled food was suspected of containing the bacteria Listeria monocytogenes that can also cause serious infection in humans and animals.

Q. Our year-old male cat, found at a county animal shelter seven months ago, has been diagnosed with eosinophilic granuloma complex (EGC). His symptoms are incessant scratching, puffy gums, blistering mouth, swollen front paw, lameness, limping. Our veterinarian has prescribed steroids for him, and these have been somewhat helpful, but can you explain this disease so that we can better understand what is going on? …

Estimates are that osteoarthritis affects 90 percent of cats over the age of 12 years. Confirmation of the disease, however, can sometimes prove elusive. In the search for an accurate diagnosis, the Winn Feline Foundation has awarded a grant, funded by the animal health company Zoetis, to researchers at the University of Melbourne. Their goal is to develop a blood test biomarker - a molecule indicating an abnormal process - so the disease can be identified earlier.

If your cat has become unresponsive to everyday sounds, squeaky toys or his name, if he doesnt know youre in the room unless you touch him, or if a loud noise fails to awaken him, a veterinary visit should be scheduled to determine if hes losing his hearing. Hearing is a vital sense for cats and greatly contributes to their self-preservation and comfort with us. Deafness in cats can be caused by a wide variety of conditions.

Human medicine has made strides in identifying clinical risk factors in heart disease. Now veterinary research hopes to do the same for hypertrophic cardiomyopathy in cats. It’s the most common feline heart disease and cause of cardiovascular death.

The results of studies on the life expectancy of cats with diabetes mellitus have varied widely. Now research among several European veterinary colleges, including the University of Zurich, has found cats with the disease have fair to good prospects for survival. The retrospective study of 114 cases, reported in the Journal of the American Veterinary Association, showed the median survival time of cats newly diagnosed with the disease was one year and 46 days, while 70 percent lived longer than three months, 64 percent lived longer than six months and 46 percent lived two years.

The sad truth about cats’ access to veterinary care in the U.S.: They don’t have much. Surveys show that nearly twice as many dogs visit the veterinarian as cats, even though the cats outnumber dogs — 86 million versus 78 million. Thirty-nine percent of owners say they would take their cat to the veterinarian only in the event of illness; and 60 percent report that their cat hates going to the veterinary clinic. The visits may stress both owners and cats, says the American Association of Feline Practitioners. To offer a more calming, encouraging environment, it has launched an initiative to improve cats’ treatment, handling and overall health.

A specific gene affecting a mouse’s sense of smell helps it avoid predatory cats, according to research at Northwestern University. Neurobiologist Thomas Bozza, Ph.D., and his team found that removing an olfactory receptor responsible for detecting certain odors can impact a mouse’s survival. The gene, TAAR4, controls production of a receptor that detects a substance concentrated in carnivores’ urine. Usually, mice avoid the scent marks of predators, but those lacking the TAAR4 gene do not — and can end up as prey.

Ticks pose a year-round threat to cats in every state — even if yours spends virtually all his time indoors. These minute arachnids have survived for millennia and often go undetected as they feed on their host’s blood, often causing serious illness and even death. “The major problem with ticks is that they are vectors for various infectious agents,” says dermatologist William H. Miller, VMD, at the Cornell University College of Veterinary Medicine.

Treatment of oral squamous cell carcinomas (OSCC) has traditionally relied upon surgery, chemotherapy and/or radiation — with disappointing results. Cats with the rapidly spreading cancer, which accounts for 10 percent of all feline tumors, suffer pain when eating, drinking, grooming and breathing. Many are in such distress that they are euthanized.

Young kittens may seem fearless when they demonstrate their acrobatic talents during play, but they’re no match for the potentially deadly disease feline panleukopenia. Sometimes referred to as feline distemper, the disease is caused by the feline panleukopenia virus (FPV). The highly contagious, hard-to-kill virus can spread from infected cats or kittens to other kittens or adult cats who haven’t been vaccinated against it. In addition, recent studies confirm that there has been crossover of the infectivity between cats and newer types of parvovirus usually found in dogs. Parvo Crossover. While some newer canine parvovirus strains can transmit the viral disease to unvaccinated cats, this does not appear to cause disease in most cases, and also does not appear to occur at a rate to cause alarm because the current vaccines used in cats provide protection.
