Understanding
high blood pressure in cats

Cats, just like people, commonly suffer from high blood pressure, especially as they get older. In fact around 15% of cats over 9 years old have high blood pressure.

The information below will help you understand high blood pressure, common causes of high blood pressure in cats, and what affect it can have if left untreated.

Why does my cat have high blood pressure?

In healthy cats complex systems within the body make constant adjustments to keep blood pressure within a healthy range.

If there is a problem affecting any of these systems, a cat’s body is unable to maintain blood pressure within the normal healthy range.

What causes high blood pressure?

High blood pressure can occur on its own for no obvious reason, but in cats it is normally due to an underlying condition. Chronic kidney disease and hyperthyroidism (overactive thyroid) are the most common conditions associated with high blood pressure in cats.

What does this mean for my cat?

Sustained high blood pressure can cause damage to the eyes, kidneys, heart and brain. Sometimes there may already be some damage to these organs, especially if the blood pressure is very high or has been high for a long time.
