Can cats and dogs have blood pressure problems?

Yes. Systemic hypertension is particularly important in older cats and pets with kidney, endocrine, or cardiovascular disease. Low blood pressure can also occur with shock, anesthesia, severe illness, or dehydration.

The key takeaway

One stressed reading is not always enough. Technique, cuff size, patient position, environment, and repeated measurements affect interpretation.

Why high blood pressure matters

Persistent hypertension can injure target organs, especially the eyes, kidneys, brain, and cardiovascular system. Sudden blindness from retinal damage can be one of the first signs in a cat.

Which pets should be screened?

Senior cats, pets with chronic kidney disease, hyperthyroidism, endocrine disease, certain cardiac conditions, and animals with signs compatible with target-organ damage are common candidates for blood-pressure assessment.

How is it measured?

Veterinary teams generally use Doppler or oscillometric devices with a properly sized cuff. Several readings are taken after the pet has had time to settle. Trends and clinical context are more meaningful than a single number obtained during severe anxiety.

How is hypertension treated?

Treatment depends on severity, underlying disease, and evidence of organ damage. Medication may be needed, and follow-up measurements are important because excessive lowering can also be harmful.
