Disease

A new test for chronic kidney disease in cats has identified its onset an average of 17 months earlier than existing methods, according to a small study published in the Veterinary Journal. Researchers at Oregon State University and IDEXX Laboratory developed a biomarker - a substance indicating disease called SDMA - and used it in a controlled study of 32 older but otherwise healthy cats. When available commercially, a test based on the biomarker could alert cat owners and veterinarians to kidney disease through periodic checkups, researchers say.Chronic kidney disease is common in geriatric cats and often causes their death, says researcher Jean Hall, DVM, Ph.D., at Oregon State. Damage from it is irreversible, but this is an important advance, in that we should be able to identify the problem earlier and use special diets to slow the disease.

These are among the treatments that veterinarians increasingly use to improve cats well-being:

By far the most common heart disease in cats is hypertrophic cardiomyopathy (HCM). The characteristic thickening of the muscle of the left ventricle seen with HCM affects the hearts ability to pump blood. One complication is that blood clots form and dislodge from the heart and block blood flow in large arteries. The clots cause pain, nerve and muscle damage, and can lead to death. Treatment today is only minimally effective.A study led by Fern Tablin, VMD, Ph.D., at UC Davis will analyze the activation of blood platelets - cells that help blood clot - in cats with HCM with the goal of early detection of the disease. Many affected cats show no signs. Others have labored or rapid breathing and lethargy.

Advances in veterinary medicine and an increase in animal blood banks have improved the diagnosis and treatment of hemophilia to the extent that some cats who once would have died from the life-threatening disorder can now live full lives.

My 12-year-old cat has hyperthyroidism. She cannot tolerate methimazole, and I have tried special food (she didnt like it), homeopathic treatments, dietary additives and even consulted an animal psychic. Nothing has an effect, and I dont want to put her through surgery or radioactive iodine therapy. They both sound horrible and also too expensive. Have we run out of options?

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.
