Short Takes

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.

Surgeons at the University of Georgia Veterinary Teaching Hospital have used a Siamese cat’s stem cells to improve acceptance of his kidney transplant. The recently announced surgery on 4-year-old Arthur, performed in May, is the hospital’s second successful kidney transplant using feline adult stem cells.

Researchers at North Carolina State have launched a study to determine if probiotics can protect kittens from deadly gastrointestinal disease. More than 15 percent of kittens at animal shelters in the U.S. die or are euthanized before 8 weeks of age because of illness. The majority have diarrhea or GI diseases, says the Winn Feline Foundation, sponsor of the study.

We may think our cats have it easy, being fed and loved while living safely indoors, but nutritionist Tony Buffington, DVM, Ph.D., at Ohio State University College of Veterinary Medicine says cats can have a different perspective:

Spending on pets will reach $59 billion this year, up 4.9 percent over 2013, according to the American Pet Products Association. The surprising category with the greatest proportion of growth last year: pet services such as boarding, training, pet sitting and grooming. It grew by 6 percent to $4.4 billion.

The placebo effect has been the subject of frequent research in human medicine, with results ranging from the psychological — you expect to feel better taking a medicine and you do — to the physiological — endorphins in the brain and spinal fluid caused your improvement.

A three-year retrospective study of people who went to the Mayo Clinic Hospital in Rochester, Minn., with cat bites to their hands found that 30 percent of them required hospitalization. While dog bites can seem dramatic, with torn skin, broken bones and considerable bleeding, their open wounds can often be easier to clean — and heal.

Veterinarians are increasingly using a human drug to prevent arterial thromboembolism — a blood clot interrupting blood flow — in cats. The clots are common in feline heart disease, and their presence carries a guarded to poor prognosis: more than 60 percent of cats don’t survive them. In addition, because cats who do survive often develop a second clot, usually causing extreme pain and paralysis of the rear limbs, many are euthanized.

A lack of knowledge about cats’ reproduction and the myth that cats should have a first litter before spaying may lead to 200,000 accidental litters — and more than 850,000 kittens — annually in the U.K.

The American Pet Product Manufacturers Association issues its National Pet Owners Survey every two years — a real door-stopper with more than 500 pages. The findings are intended for businesses, marketers and media. Here’s a sampling from the 2013-14 section about cat owners, who comprise 37 percent of U.S. households.

Do you know what message your cat sends when his tail stands upright? A survey of 1,100 owners in England found that 75 percent of them didn’t realize that an upright tail meant the moggy — their slang for cat — was sending a greeting.
