A cat that paces the hallway at 2 a.m. is usually not being difficult. Three causes cover most of it: cognitive decline, pain or lost senses, and a body clock that is 2 hours out of step with the house. The plan is 12 hours of real light, 12 hours of real dark, 4 weeks of scoring and 2 vet lines, and it works better than any night-time punishment.
The 3 causes, and what each one looks like
Cognitive dysfunction shows up as a cluster: waking at 2 or 3 a.m., yowling in a room with nobody in it, staring at a wall, soiling outside the box, and getting stuck behind a door. Pain and lost senses look different: arthritis shows as hesitating 2 seconds before a 40 cm jump that used to be easy, and it is common in cats over 12; high T4, kidney disease and blood pressure over 160 mmHg all disturb sleep, and a cat that cannot hear its own name stops responding to being called at night. The third cause is the clock: a cat that sleeps 16 hours in daylight, eats 1 large meal at 6 p.m. and lives under a 5 to 20 lux lamp all night has no reason to be awake at noon and asleep at midnight.
12 hours light, 12 hours dark
Split the day into 3 bands. From 07:00 to 19:00 the cat needs 500 lux or more at eye level: a window with 2 hours of direct sun does it, or a 10 watt 6500 K lamp at 1 metre, switched on for the cat rather than the room. From 19:00 to 22:00 drop to 50 to 100 lux, which is a normal living room with the overhead light off. From 22:00 to 07:00 keep the room under 5 lux and put a 1 to 3 lux night light in the hallway so the cat can still find water and the box. Two weeks of that, 7 days a week, is the minimum before judging it, and the first change is usually earlier sleep, not less waking.
4 weeks of scoring
Score 4 numbers every morning, in under 2 minutes: how many separate walks happened between 23:00 and 06:00, total minutes out of the bed, whether there was yowling, and whether the cat seemed oriented when you got up. A week of that gives 1 row for the table below; 4 weeks gives a trend, and a trend is what separates a bad week from a disease. A 50 percent drop by week 4 is a normal response to light and feeding changes; no change at all after 4 weeks means the next step is blood work, not a stronger night light.
| Week | Nights scored | Walks per night | Minutes awake | Score 0 to 3 |
|---|---|---|---|---|
| 0, baseline | 7 | 4 | 90 | 3 |
| 1, light change | 7 | 3 | 70 | 3 |
| 2, feeding change | 7 | 2 | 45 | 2 |
| 3, play added | 7 | 2 | 30 | 1 |
| 4, target | 7 | 1 | 15 | 1 |
2 vet lines
Same day: sudden blindness, head pressing against a wall, a seizure, yowling that gets worse when you touch the belly or hips, no urine for 24 hours, a cat that cannot settle for even 1 hour, or new aggression toward a person it knows. Within 1 to 2 weeks: 2 or more walks per night for 7 nights in a row, weight down 5 percent in 30 days, water over 60 ml per kg per day, new soiling, or a T4 and blood pressure that have never been checked on a cat over 11. The second line is not urgent, but it is the one that finds the thyroid and the kidney cases early.
Room setup for the night shift
Keep 3 clear paths from the bed to the box, the water and the food, with no rug edge to trip on. Put 2 night lights at 1 to 3 lux, 1 in the hallway and 1 near the box. Move the box within 1.5 metres of the sleeping spot if the cat is 14 or older, add 1 ramp at 15 cm to the favourite chair, and keep 3 water bowls, because a cat with kidney disease drinks in small visits. A heated bed at 30 to 35 Celsius reduces the stiffness that makes a cat get up and walk in the first place.
What not to do
Do not shut the cat in a bathroom or the basement: 8 hours of isolation raises stress, yowling and house soiling, and it hides the signs you need for the vet. No sedative, melatonin, valerian or human sleep aid without a prescription, because cats metabolise several of these slowly and the effect on an old liver is unpredictable. Do not leave a 20 lux night light on all night; that is bright enough to suppress the dark signal the plan depends on. Do not feed the largest meal at 23:00, which simply moves the waking up 3 hours later.
Feeding and play, in clock terms
Split food into 4 to 5 meals: 07:30, 12:00, 17:00, 21:00 and a small 200 kcal-free top-up is not needed, but the 21:00 meal should be the second largest, not the largest. Two play sessions of 8 to 10 minutes at 09:00 and 20:00, ending with a small feed, mimic the hunt-eat-groom-sleep order that a cat's day runs on. Keep the house quiet from 22:00 and do not answer a yowl with light and conversation, because attention at 3 a.m. is a reward that trains the next 3 a.m.
Cost, and the 1 test worth doing first
A senior panel with total T4, a urine check and blood pressure runs about 120 to 300 dollars at most clinics, and it is the highest-yield 1 hour you can spend on a night-waking cat: thyroid, kidney and pressure problems explain a large share of cases that look behavioural. Imaging and a cognitive workup cost more and come later. The cost calculator splits the panel by test, and the light routine pairs with the night light setup.
First 7 days
- Day 1: start the 4 number morning score; 2 minutes, 1 line per day.
- Day 1: set lights to 07:00 to 19:00 bright, 22:00 to 07:00 under 5 lux.
- Day 2: move 1 night light to the hallway at 1 to 3 lux and 1 near the box.
- Day 3: split feeding into 4 meals, with the 21:00 meal second largest.
- Day 4: book the senior panel with T4, urine and blood pressure.
- Day 7: count walks per night for the week and compare with baseline 4.
Yowling is a separate problem with its own causes, and the vocalization guide covers the hearing, thyroid and pain angles. If the walking happens with yowling and no orientation, treat it as the cognitive cluster and move the vet visit from 2 weeks to 1.

Frequently asked
Will a night light stop my old cat pacing?
Not on its own. The light plan needs 12 hours of 500 lux or more by day and under 5 lux at night, and a 1 to 3 lux hallway light only prevents bumps. Expect a 50 percent drop in night walks by week 4, not in 2 nights.
How do I know if it is cognitive decline or pain?
Pain usually comes with a change in movement: hesitating before a jump, a stiffer walk, yowling when the hips are touched. Cognitive decline comes with disorientation, staring at walls and soiling. Blood work and a blood pressure check separate them.
Is it cruel to leave an old cat in the dark?
No, provided the dark period is 9 hours and there is a 1 to 3 lux light on the route to water and the litter box. Total darkness for 24 hours is stressful, but a real dark phase is what rebuilds the day and night pattern.
