Other than the unlikely use of goggles, one of the best ways to protect your cats vision is to pay attention to his behavior. If hes squinting or rubbing his eyes, he could have a corneal ulcer. The painful condition is caused by an erosion of the layers of the cornea, the translucent outer covering of the eye.Yet another telling sign is a discharge from the eye. This can range from tearing to a thick secretion. An opaque white, yellow or blue coloration may also be noticeable. Eventually, the discoloration and a cloudiness of the cornea can prevent light from entering the eye and result in blindness.

One common reason for veterinary visits among cats is otitis externa, or inflammation of the external ear canal. Most people believe that that the term otitis externa means an ear infection, but that isnt true. Something has to breech the normal defense mechanism of the ear to trigger the infection, says veterinary dermatologist William H. Miller, Jr., VMD, Medical Director of the Cornell University Hospital for Animals. Once the surface of the ear canal is damaged, bacteria or yeast inside and around the canal can cause an infection. The underlying causes can include tumors, allergies, ticks or fleas, and excessive grooming and ear wax. But by far the most frequent cause in cats, especially kittens, is ear mites.

The cornea, the clear coating of the eye that admits light, has layers of specialized skin cells, including:

The cats hip problem was so painful that he required a femoral head osteotomy, the surgical removal of the top of the thighbone forming the ball and socket joint. Afterward, the supporting muscle needed to be strengthened to bear the cats weight, but he refused to use his limb.

The solution: Exercise in an underwater treadmill twice a week for two or three weeks. Movement is easier underwater, and the resistance of the water helps strengthen muscle. It got the cat jump-started into using the leg better, says Joseph Wakshlag, DVM, Ph.D., one of 83 specialists in the U.S. certified by the American College of Veterinary Sports Medicine and Rehabilitation. He heads the Sports Medicine and Rehabilitation service at Cornell University Hospital for Animals.

Animal shelters in the U.S. take in 3.4 million cats annually and euthanize 1.3 million of them. Two shelter medicine programs have set out to save many of those lives with the launch of the Million Cat Challenge.The Koret Shelter Medicine Program at UC Davis, Maddies Shelter Medicine Program at the University of Florida and hundreds of animal shelters throughout North America want to challenge animal control facilities and private shelters to reduce euthanasia.

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.

If your cat needs to have anesthesia, you can rest easier about the procedure because it poses fewer risks today, thanks to newer drugs, precise monitoring and an increased number of board-specialized veterinarians.Our discipline has evolved, says Luis Campoy, LV CertVA, MRCVS, Section Chief of Anesthesiology at Cornell University College of Veterinary Medicine.

Guidelines from the American Veterinary Medical Association understandably take an objective approach to euthanasia: When animals are plagued by disease that produces insurmountable suffering, it can be argued that continuing to live is worse for the animal than death … The humane disposition is to act for the sake of the animal or its interests, because … the animal will be relieved of an unbearable burden.

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?

Hemophilia occurs as a result of genetic mutation, and once it develops, it can be transmitted to a cats offspring. Because female carriers are asymptomatic (meaning they dont show any symptoms), it can be challenging to identify them to avoid passing the hemophilia mutation onto the next generation.

In little more than a decade, changes have taken place in veterinary medicine to help prevent cats developing malignant tumors at the site of certain vaccinations. However, 22,000 cats in the U.S. still develop injection site-associated sarcomas (ISAS) every year, and the tumors are often more aggressive and prone to recurrence than spontaneous ones.
