Why Is My Cat Meowing Excessively? UK Medical & Behaviour Causes

Published Last updated 4 min read

Quick answer

Some breeds — Siamese, Oriental, Burmese — are naturally talkative. Sudden increase in loud meowing, especially at night in older cats, often signals illness: hyperthyroidism, high blood pressure, pain, or cognitive decline. Intact females yowl when in heat. Always rule out medical causes before treating as attention-seeking behaviour.

Normal talkers vs concerning vocalisation

Normal:

  • Greeting meows when you come home
  • Requesting food at usual meal times
  • Brief chirps at birds through the window
  • Breed-typical chattiness throughout life

Concerning:

  • New or much louder meowing in a previously quiet cat
  • Night crying waking the household — common in senior cats
  • Repetitive yowling with pacing or disorientation
  • Vocalisation with not eating, hiding, or litter tray changes
  • Straining to urinate with crying — male cats especially — emergency

Common causes

CauseTypical pattern
HyperthyroidismSenior cat, weight loss despite good appetite, night vocalisation
HypertensionOlder cat, sudden blindness signs, yowling
Pain — arthritis, dentalMeowing when jumping, eating, or touched
Cognitive dysfunctionNight wandering, confusion — Cat cognitive dysfunction
Urinary pain / FLUTDVisiting tray often, blood in urine — FLUTD cats UK
Heat (intact female)Loud yowling, rolling, raising hindquarters
Attention / hungerMeows at fridge, follows you, stops when fed
DeafnessVery loud meow, no response to sounds

Medical causes in senior cats

According to the PDSA, hyperthyroidism is one of the most common reasons older cats become loudly vocal at night. Excess thyroid hormone speeds metabolism — cats feel hungry, restless, and sometimes anxious. Blood tests diagnose it; treatment is usually effective.

High blood pressure often links with kidney and thyroid disease — it causes headache-like discomfort and sudden vision loss. Yowling may be the first sign owners notice.

Behavioural and environmental causes

  • Boredom in indoor-only cats without climbing and hunting play
  • Learned behaviour — meowing produced food or attention in the past
  • New pet or baby — stress vocalisation
  • Empty bowl at 3 am — predictable hunger cries

Cats Protection recommends predictable routines and enrichment once medical issues are excluded.

When to see a vet urgently

Emergency care if meowing occurs with:

  • Straining or crying in the litter tray — blocked bladder risk in males
  • Collapse, open-mouth breathing, or extreme lethargy
  • Sudden blindness — bumping into furniture, dilated pupils
  • Not eating for 24 hours — especially overweight cats — liver risk

Book a vet appointment within days for new night vocalisation in cats over 8 years, or any persistent change lasting more than a week.

Home monitoring

Keep a diary for one week:

  • Time of day vocalisation peaks
  • Triggers — feeding, doorbell, loneliness
  • Appetite, weight, thirst — see Cat drinking lots of water
  • Litter tray use — frequency, blood, straining
  • Sleep and confusion — getting lost in familiar rooms

Video a vocalisation episode if safe — helps your vet distinguish pain, dementia, and heat behaviour.

Do not:

  • Punish or shout — increases stress
  • Assume senility without blood tests
  • Delay male cats with urinary signs — minutes matter

What your vet may recommend

Physical exam, blood pressure measurement, blood and urine tests, and thyroid checks. Treatment targets cause — thyroid medication, pain relief for arthritis, dental care, or urinary management.

For behavioural cases after medical clearance:

  • Scheduled feeding — puzzle feeders before bed
  • Play sessions before your bedtime
  • Safe night routine — quiet room, litter, water
  • Referral to a clinical animal behaviourist if needed

Frequently Asked Questions

Why does my cat meow at night?
Hunger, boredom, dementia, hyperthyroidism, and pain all cause night calling. Senior cats with new night vocalisation need a vet check — medical causes are common and treatable.
Do deaf cats meow louder?
Often yes — they cannot hear their own volume and may yowl more. Deafness itself is not harmful, but sudden vocal changes in older cats still warrant blood tests for thyroid and kidney disease.
Can pain make cats vocal?
Yes — arthritis, dental disease, and urinary obstruction cause crying. Male cats straining in the litter tray with vocalisation need emergency care — see FLUTD guide.
Should I ignore excessive meowing?
Only after your vet rules out medical causes. Ignoring pain-related crying delays treatment. Once cleared medically, behaviour plans and enrichment address attention-seeking.
