Why your cat’s blood pressure matters more than you might think

Most of us understand the importance of checking our own blood pressure. It’s quick, painless, and can reveal problems long before we feel unwell.
But did you know the same is true for cats?
High blood pressure (hypertension) in cats is surprisingly common, particularly as they get older. The challenge is that it’s often a silent condition. Many cats show few obvious signs until complications develop, which is why routine checks can make such a difference.

The “silent” problem in older cats
High blood pressure in cats is frequently linked with other common conditions, such as chronic kidney disease or hyperthyroidism, especially in middle-aged and senior cats.
Because the signs can be subtle, hypertension may only be discovered when more serious problems occur. These can include:
Sudden blindness caused by retinal damage
Neurological signs such as seizures or disorientation
Worsening kidney disease
Changes in the heart and blood vessels
This is why we often refer to hypertension as a “silent killer.”
The good news is that, when detected early, it’s usually very manageable.
Why screening makes a real difference
Research suggests that many cats with hypertension are only diagnosed once symptoms appear, even though routine screening could detect the problem earlier.
We can measure your cat's blood pressure easily.
Cats diagnosed through screening often have better outcomes and longer survival than those diagnosed after clinical signs appear.
In other words, a simple test can help us catch problems before they cause lasting damage.
What happens during a blood pressure check?
A blood pressure check for your cat is quick and non-invasive. It’s very similar to what happens at your own GP appointment.
We will:
Place a small cuff around your cat’s leg or tail
Use a specialised monitor to measure blood pressure
Take several readings to get an accurate average
Most cats tolerate it well, especially if they can stay relaxed in their carrier or on a comfortable surface.
If high blood pressure is found
Treatment is often straightforward and effective.
Most cats are managed with daily medication, commonly a drug called amlodipine, which lowers blood pressure by relaxing blood vessels.
Sometimes other medications may be used alongside it, particularly if a cat also has kidney disease or protein in the urine.
With treatment and regular monitoring, many cats can enjoy good quality of life for years.
Which cats should be checked?
Blood pressure checks are particularly important for:
Cats over seven years old
Cats with kidney disease
Cats with hyperthyroidism
Cats with sudden vision changes
Cats showing unexplained behavioural or neurological signs
Even healthy-looking older cats benefit from routine screening.
This simple check could protect your cat’s health
We regularly check our own blood pressure because it helps us stay healthy. The same principle applies to our pets.
A quick blood pressure check could detect a problem early, prevent complications like blindness, and help your cat live a longer, healthier life.
