The lowdown on cats' high blood pressure

Q: My cat is 9 years old. At her recent annual exam, her veterinarian suggested checking her blood pressure. I didn't know cats could get high blood pressure. Is it a common problem?

A: High blood pressure, or hypertension, is the most important cardiovascular disease seen in senior cats. The condition is most often seen in cats 7 years and older. Among the causes of hypertension in cats are chronic renal (kidney) disease, diabetes and hyperthyroidism. Cats with hypertension may show signs, such as seizures or circling, heart enlargement or murmurs, and eye problems.

A cat's blood pressure can be measured at the front leg, the back leg or the tail. Many doctors like using the tail because the cat can bury his head in the owner's arms during the procedure, allowing him to feel more comfortable. The front leg is a second choice. If they are treated, the prognosis is good for cats diagnosed with hypertension. Medication is available to help reduce blood pressure to a normal level and to control the heart rate.

Your veterinarian also may suggest ways to correct conditions that may be causing hypertension, or recommend a switch to a renal or senior diet to reduce sodium intake. It's also important to ensure that the cat always has plenty of fresh water. No data suggest that fat cats are more prone to hypertension, but being overweight most likely isn't good for them.
