Cat Hypertension: Detection and Treatment

Hypertension in cats frequently goes undetected until serious organ damage occurs. Early diagnosis and treatment can preserve quality of life.

Key Facts

Feline hypertension is defined as sustained systolic blood pressure above 160 mmHg
Over 60% of cats with chronic kidney disease develop secondary hypertension
Untreated hypertension causes blindness through retinal detachment
Amlodipine is the first-line antihypertensive treatment for cats
Senior cats should have blood pressure checked at least annually

Welfare Considerations

Hypertensive cats often suffer silently — by the time signs are obvious, blindness or neurological damage may already have occurred. Blood pressure measurement in cats requires a calm environment and acclimatisation time; anxious readings can be falsely elevated. Once diagnosed, lifelong medication is typically needed and owner compliance is critical. Regular monitoring appointments allow dose adjustment and early detection of target organ changes.

What You Can Do

Request blood pressure measurement at your cat annual or biannual health check
Watch for signs like sudden blindness, head pressing or seizures and seek emergency care
Give antihypertensive medication consistently at the same time each day
Keep follow-up monitoring appointments even if your cat seems well
Work with your vet to manage underlying conditions like kidney disease or hyperthyroidism
