Disease

Would you be able to provide at-home care for your cat? Heres what to consider.

Like their human counterparts, feline lungs are bag-shaped, elastic organs, two in number, located on either side of the heart and occupying most of the space in the chest cavity. They are virtually identical in structure to human lungs as well, functioning in the same manner and fulfilling the same fundamental purposes - removing carbon dioxide from the bloodstream and keeping the blood constantly supplied with life-sustaining oxygen. The lungs perform their vital functions by means of two processes - ventilation and perfusion - explains Richard Goldstein, DVM, an associate professor of small animal medicine at Cornell Universitys College of Veterinary Medicine.

Your cat Pinky has enjoyed good health for most of the eight years shes spent in your home. Lately, however, shes been undergoing some worrisome changes. Shes eating and drinking much more than she used to; shes recently begun to develop a potbelly; and shes become uncharacteristically lethargic. While such changes could be attributable at least in part to her advancing age, they are also signs that Pinky could be afflicted with a disorder called hyperadrenocorticism, otherwise known as Cushings disease. According to Deb Zoran, DVM, PhD, an associate professor of medicine at Texas A&M Universitys College of Veterinary Medicine and Biological Sciences, this condition is extremely rare in cats - far less frequently diagnosed than it is in dogs. Nevertheless, cat owners should be aware of Cushings disease, its causes, the clinical signs associated with it and the treatment options available.

Dear Elizabeth, I am an elderly cat owner. Im old and so is my girl, Pearl. Over the years, we have gotten used to many changes in visits to our veterinarian. For example, Pearls "yearly shot" is no longer annual, and screening lab work is an expected part of her exam. These changes have been explained to me and I accept them, but there is one thing I just cant get used to. Years ago our vet would take a few minutes on the exam table to clean Pearls teeth. Pearl didnt like it much, but the vet was able to take care of her teeth without anesthesia right in the office. Now, that office procedure just isnt offered; instead our vet is recommending anesthesia for dental cleaning. Pearl has visible tartar on her teeth, but why cant my vet just clean them in the exam room?

Despite their relatively small size, your cats kidneys play a huge role in many life-sustaining processes.These two bean-shaped little organs - situated just behind the cats rib cage, one on either side of its spine - filter waste from the blood. In doing so, they also help control blood pressure and regulate the amount and chemical consistency of fluid in the bloodstream. In addition, they produce a variety of vitally needed hormones and enzymes and contribute to the production of red blood cells. Since about 25 percent of the blood that enters your cats circulatory system with each heartbeat travels directly to the kidneys, their well-being is essential to your cats health. Unfortunately, feline kidneys are vulnerable to a wide range of serious disorders. Indeed, kidney (renal) disease is a major cause severe illness and death in cats, especially after the age of seven years.

While casually petting your cat, you notice a small lump on its neck or behind one of its knees. What you may have discovered is a swollen lymph node. You dont have to be overly alarmed. The eruption is most likely a harmless and transient indication that the animal has a minor infection, and the swelling is likely to subside within a day or two. Nevertheless, youd do well to take your cat to your veterinarian for a checkup of its lymphatic system, the complex network of glands and tiny vessels that transport life-sustaining substances throughout its body. In some instances, a swollen lymph node may be a sign that the animal is harboring a potentially deadly disease.

The last time Frannie, the ShortTakes office feline, had her annual exam, we asked about heartworm control. The vet said that, as long as Frannie continued to be a strictly indoor cat living in this region (upstate New York), heartworm medication "probably isnt necessary." But ask again when Frannie comes back in six months, the vet added, "because things might change." We had been thinking about the late Dr. Jim Richards, an outspoken crusader for heartworm protection - no matter where in the 50 states a cat might live. All it takes is one mosquito, biting a heartworm-infected dog - then passing the disease on to the next cat it bites -to cause HARD (heartworm-associated respiratory disease), Dr. Richards said again and again.

The American Lung Association defines secondhand smoke, also known as environmental tobacco smoke, as a mixture of the smoke exhaled from the lungs of smokers and the smoke that is given off by the burning end of a cigarette, pipe or cigar. These ambient fumes, which can linger in the air for hours after the source has been extinguished, will then be involuntarily inhaled by nonsmokers - with potentially deadly consequences.

If you have your female cat spayed at an early age, you will, of course, be preventing her from experiencing motherhood. Nevertheless, youd be wise to have her undergo the procedure, since youll also be dramatically lessening the chances that she will be afflicted with mammary cancer later in her life (not to mention helping to curb feline overpopulation). Indeed, says Margaret McEntee, DVM, an associate professor of oncology at Cornell Universitys College of Veterinary Medicine, having your cat spayed at six months of age will reduce her chances of getting mammary cancer by about 90 percent.

Red and swollen gums, bad breath, declining appetite and weight loss are among the conspicuous indications that your cat is suffering from a disorder centered in its mouth, most likely in its teeth and gums. The animal may not appear to be in pain, but thats because cats are very good at concealing illness, possibly because they dont want to signal a potential predator that they are weakened and are thus vulnerable to attack.

Among all causes of severe feline disease, none is more prevalent than feline leukemia virus (FeLV), a submicroscopic organism associated with the illness and death of more cats worldwide than any other infectious agent. This virus - which is spread through the urine, saliva, nasal secretions or milk of infected animals - is currently recognized as the chief causative agent of fatal infectious disease among U.S. domestic cats.

Each year, many thousands of cats are brought to veterinary clinics throughout the U.S. showing the telltale signs of respiratory distress: labored breathing, chest constriction, wheezing and coughing. In the vast majority of cases, the animal will be diagnosed with asthma, a mechanical constriction of the airways, or bronchi, the narrow network of tubes that lead directly from the trachea to the lungs. The narrowing of the airways occurs when a cats immune system overreacts to the presence of an allergy-producing substance, such as cigarette smoke, dusty kitty litter or pollen and responds to the presence of the allergen by releasing stimulants that cause a swelling of the tissue (mucous membrane) lining the bronchi.
