Why Senior Cats Yowl at Night (and How to Get Everyone Sleeping)

It's a symptom, not a quirk

Loud night-time vocalising that starts in a cat's senior years is one of the most reported and most ignored symptoms in feline medicine. The shortlist: hyperthyroidism, high blood pressure, cognitive decline, hearing loss, and pain. All are diagnosable; most are treatable.

The big three to test

Hyperthyroidism classically causes night yowling plus weight loss despite a big appetite. High blood pressure — often secondary to kidney disease — causes headaches and disorientation cats express vocally. Both are simple to test for. Cognitive dysfunction (feline dementia) is a diagnosis of exclusion after those are ruled out.

What helps at home

A night light in the hallway helps confused or dim-sighted cats orient. A warm bed near yours reduces separation confusion. A late-evening feed helps some cats settle. Responding calmly and briefly beats both ignoring and fussing — you're reassuring, not rewarding.

Don't just soundproof it

The temptation is earplugs and a closed door. But night yowling that gets written off as old age is often the only visible sign of a condition that's very manageable — and the earlier the bloodwork happens, the better every option is.
