Cats are independent, not self-sufficient. They cope better with being left than dogs, but the difference is in hours, not weeks, and the risk is rarely boredom — it is a water bowl knocked over, a litter tray they refuse to use, or an illness nobody notices for two days.
How long is reasonable
A healthy adult cat is generally fine alone during a normal working day, and can manage overnight with plenty of water, food and a clean tray. Beyond roughly 24 hours, someone should be checking in daily. Most UK veterinary and welfare guidance is clear that cats should not be left without a visit for more than a day at a time.
Kittens, elderly cats, cats on medication and cats with kidney, urinary or diabetic conditions need a visit at least once and often twice a day, regardless of how independent they seem.
What to prepare before you go
Set this up the day before rather than as you leave, so you can spot a problem in time.
- Two or three water sources in different rooms, in wide, heavy bowls that cannot tip
- One litter tray per cat plus one spare, all scooped and topped up
- Food measured out for whoever is visiting, with clear written instructions
- Medication in a labelled container with doses and times written down
- Windows on restrictors, washing machine and tumble dryer doors shut, blind cords tied up
- Anything toxic put away: lilies and other cut flowers, cleaning products, human medicine
- Your vet's details, your cat's microchip number and an emergency contact left visible
Sitter visits, boarding or a friend?
Most cats do best in their own home. Territory is what they are attached to, and moving them to a cattery adds a stressor on top of your absence. Drop-in visits from a sitter keep the routine intact, allow someone to spot a problem, and let you get a photo each day.
Boarding makes sense when a cat needs supervised medical care, when your home is being worked on, or when there is no one able to visit. Whoever it is, do a handover visit first so the cat has met them before you leave.
Food and water while you are away
An automatic feeder is useful for dry food and portion control, but do not rely on it alone: they jam, and a cat can empty a large bowl on day one and go hungry on day three. Wet food should never be left out for more than a few hours, especially in summer. A water fountain encourages drinking, which matters most for older cats, but still leave standing bowls in case it fails.
Signs your cat has not coped
Watch for these when you return, and call a vet rather than waiting if you see any of them: not eating for more than a day, straining in the litter tray or urinating outside it, hiding and refusing contact for longer than a few hours, over-grooming to the point of bald patches, or noticeably drinking more than usual. A cat that has not urinated at all needs urgent veterinary attention.
Coming home
Do not make a fuss. Let the cat come to you, keep the first evening quiet, and go straight back to the normal feeding routine. Most cats settle within a day; if yours is still off after 48 hours, that is a vet conversation, not a behaviour one.
Common questions
- Can I leave my cat for a weekend?
- Not without someone visiting. Two nights alone is beyond what most welfare guidance considers reasonable, and a single mishap with water or litter has 48 hours to go wrong.
- How often should a sitter visit?
- Once a day is the minimum for a healthy adult cat; twice for kittens, seniors, multi-cat households or any cat needing medication.
- Do cats get lonely?
- Many form strong attachments and show it through changes in appetite, litter habits or grooming rather than obvious distress. Routine and familiar smells help more than extra toys.
