Cat Hypertension Monitoring and Treatment

Hypertension in cats causes silent organ damage until crisis events occur. Regular blood pressure monitoring in senior cats enables early intervention.

Key Facts

Hypertension affects an estimated 10-20% of cats over 10 years old
It frequently develops secondary to hyperthyroidism or chronic kidney disease
Hypertensive retinopathy causes sudden blindness through retinal detachment
Other target organ damage includes brain lesions causing neurological signs and cardiac hypertrophy
Amlodipine is the most effective antihypertensive medication for cats with excellent efficacy

Welfare Considerations

Hypertension in cats often presents dramatically with sudden blindness, which is deeply distressing for both cat and owner. Many of these crisis events are preventable through routine blood pressure measurement in cats with known risk factors including kidney disease and hyperthyroidism. Some blindness caused by hypertension is reversible if treated promptly within hours. Routine blood pressure monitoring from age 10 or at any diagnosis of chronic kidney disease or hyperthyroidism enables early treatment before organ damage occurs.

What You Can Do

Request blood pressure measurement at annual health checks for cats over 10
Seek immediate veterinary attention if a cat shows sudden blindness or disorientation
Ensure cats diagnosed with kidney disease or hyperthyroidism have regular blood pressure monitoring
Give amlodipine medication consistently if prescribed as missed doses cause pressure fluctuations
Monitor for recurrence of hypertensive signs even during treatment
