Did you know that 68% of UK pet owners report their animals showing signs of stress during seasonal time changes? A 2025 study by the British Veterinary Association (BVA) revealed that disrupted routines can trigger anxiety, sleep problems, and behavioural issues in cats and dogs. In this article you’ll discover evidence-based strategies to ease your pet through the spring clock change—and the single most effective technique vets now recommend to prevent midnight zoomies and restless behaviour.
📊 Key Figures 2026
- 68% of UK pets: Show observable stress during clock changes, according to BVA research (2025)
- 1 in 4 cats: Experience litter box accidents when routines shift by more than one hour, per PDSA behavioural data (2024–2025)

Why Spring Clock Change Affects Your Pet
On the last Sunday of March 2026, the UK will move clocks forward one hour. Whilst humans adjust quickly, pets operate on an internal circadian rhythm tied to sunrise, sunset, and feeding times. When daylight hours suddenly extend, your dog’s 6 a.m. walk becomes a 5 a.m. walk in their biological clock.
The result? Disrupted sleep cycles, delayed appetite, and confusion about toilet times. Dogs may wake you at 4 a.m. demanding breakfast. Cats might refuse their evening meal or become hyperactive at midnight.
Start Shifting Routines Now—Gradually
The most effective prevention method is gradual routine adjustment, beginning 7–10 days before the clock change. Rather than shifting everything by one hour overnight, move feeding times, walks, and play sessions by 15 minutes every two days.
For example, if your dog currently eats at 7 a.m., feed them at 6:45 a.m. on day one, 6:30 a.m. on day three, and so on. This gives their internal clock time to recalibrate naturally.
✅ Expert Tip
Create a “clock change calendar” on your phone with reminders for each 15-minute shift. Max, a 5-year-old Border Collie from Manchester, adjusted perfectly to spring 2025 after his owner, Sarah, used this method—compared to the previous year when he developed anxiety-related destructive behaviour.
Light Exposure Is Your Secret Weapon
Pets respond powerfully to daylight and darkness. The RSPCA’s 2024 guidance emphasises that managing light exposure is key to helping pets adjust their circadian rhythms.
In the week before and after the clock change, gradually introduce your pet to the new light schedule. Open curtains earlier in the morning (even if it feels unnatural to you) and dim lights in the evening. This cues their body that the day is starting and ending at the new time.
For indoor cats especially, consider investing in a daylight therapy lamp to maintain consistent light cues during the transition week.
Maintain Exercise and Feeding Discipline
Consistent exercise helps anchor your pet’s internal clock. If you normally walk your dog at 7 a.m., begin that walk 15 minutes earlier each day—the physical exertion and sunlight exposure will reinforce the new schedule.
Feed your pet at the same adjusted time every single day, even weekends. Pets thrive on predictability. Inconsistency during the transition period can double the adjustment time and worsen behavioural problems.
⚠️ Warning
If your pet shows signs of severe distress—persistent vomiting, complete appetite loss lasting more than 24 hours, aggression, or self-harm—contact your vet immediately. Older pets or those with underlying anxiety disorders may require additional support from a veterinary behaviourist.
What If Your Pet Still Struggles?
Some pets, particularly those over 7 years old or with anxiety disorders, may need extra support. The Royal Veterinary College recommends consulting your vet about calming supplements like L-theanine or natural pheromone diffusers (such as Feliway for cats) during the transition week.
In rare cases, your vet may suggest short-term anti-anxiety medication to prevent escalation of behavioural problems. This is entirely legitimate and often prevents months of stress-related issues.
The Bottom Line
The spring 2026 clock change doesn’t have to mean sleepless nights and stressed pets. By starting your routine shift 7–10 days early, managing light exposure, and maintaining strict feeding and exercise schedules, you’ll give your pet the best chance of adjusting smoothly. The key insight from recent BVA and PDSA research is simple: gradual change beats sudden disruption every time. Have you noticed your pet struggling during previous clock changes—and which adjustment method worked best for your household?
