In an effort to see what difference diet might make to an obese cats blood glucose control, researchers fed three diets-one high in carbohydrates, one high in fats, and one high in protein-to healthy-weight and obese cats and measured plasma levels of glucose, insulin, free fatty acids, and triglycerides. The study, published by BMC Veterinary Research, was done at the University of Zurich.
Were fortunate that many cats live well into their teens or even to 20 years of age or more. We generally define senior cats as any cat over 10 years of age. Geriatric cats can remain active and comfortable, but they are prone to certain health conditions. Being aware of these problems, reacting right away to changes, and providing recommended preventive care can all help keep your cat well into her later years.
Diabetes mellitus commonly strikes older, obese male cats. In its most common feline form, the pancreas doesnt produce any or enough insulin, a hormone that regulates the flow of glucose used as fuel for a variety of metabolic processes. The patient lacks nourishment, and excess glucose remains in the bloodstream, potentially damaging organs and blood vessels.
Fur, primarily made of the protein keratin, grows from follicles in the skin. While human follicles each grow a single hair, animal follicles may grow many. Each follicle has an oil gland to lubricate the skin and hair, and to keep the coat lustrous. If your cats coat turns dull and dry, you may suspect a medical problem and make a veterinary appointment. Meanwhile, you might also want to check the labels on his food.
Your cats gastrointestinal tract, like yours, is home to billions of bacteria. A healthy GI tract allows the absorption of food, while excluding toxins and disease-producing organisms. Yet malfunctions can sometimes occur. Perhaps your cat slipped outside and ingested a mouse or bird containing parasites that can cause vomiting and diarrhea.
Chronic kidney disease is common in older cats, with nearly a third of them over 12 affected and the prevalence increasing with age. The disease is incurable, involving the gradual loss of kidney function; however, owners can help slow its progression.
A promising study about supplementing with deep-sea fish oil illustrates one of the challenges in conducting research on cats and why more research is done on dogs than cats.A study of 77 dogs with osteoarthritis found that, when compared to a placebo, The fish-oil treated patients improved significantly in many of the variables … indicating a true but small relief in symptoms. Those dogs had improved in quality of life in locomotion and everyday situations, according to the report published in BMC Veterinary Research in 2012. Supplementation could be considered part of a total pain-relieving approach, especially for dogs who do not tolerate anti-inflammatory drugs, the researchers said.
Generally speaking, which supplements are beneficial for cats? Which are essential for their health, especially as they age and need to maintain mobility and cognitive ability?
Manufacturers in the $1-billion pet supplement market would like cat owners to believe that an array of their products, ranging from glucosamine to fish oil to vitamin pills, will help our cats live longer, healthier lives. Whether those supplements are actually effective is not known. Few large-scale studies have been done, and governmental oversight and regulations do not exist.Nutritionist Joseph Wakshlag, DVM, Ph.D., ACVN, ACVSMR, at Cornell University College of Veterinary Medicine believes there is little proof that many of the promotional claims about supplements are accurate; however, one study on deep-sea fish oil has shown it can be beneficial. Dr. Wakshlag, president-elect of the American College of Veterinary Nutrition, explains more about the fish oil study in the sidebar on Page 5 and on supplements in general in the following Q & A.
In our quest to eat healthy food, we often extend that enthusiasm to our cats. We evaluate their diets with the same scrupulous care we give our own, but commercial cat food can still remain somewhat of a mystery. We question if preservatives are safe. Should we avoid genetically modified ingredients? What about artificial coloring?
Treats provide welcome rewards for good behavior, but their overly generous use can contribute to obesity. One reason is that owners don’t count treats as calories. “But the bigger problem is a multiple-person household in which every time someone walks by, they give the cat a treat,” says Joseph Wakshlag, DVM, Ph.D., Associate Professor of Nutrition at the Cornell University College of Veterinary Medicine.
Beta blockers have proven effective in treating some people with hypertrophic cardiomyopathy, but their effectiveness in cats with asymptomatic HCM has not been established. However, researchers at North Carolina State University are now studying cats being treated with the beta-blocker atenolol to better determine if early medical therapy improves their quality of life.
