Cats are often seen as low-maintenance, self-sufficient pets. It's true—they don't need to be walked or entertained 24/7. But that doesn't mean they enjoy being left alone for long stretches.
So how long is too long?
According to feline behaviourists and veterinary sources, most adult cats can safely be left alone for up to 24 hours but after that, things start to get more complicated.
The 24-Hour Rule
“A healthy adult cat can generally manage alone for a day—as long as they have access to clean water, food, and a clean litter box.”
— American Veterinary Medical Association (AVMA)
This is the often-cited baseline. If you're away for a single day, and everything at home is in order, your cat is likely to be fine. But even then, it's important to consider variables:
- Are they used to being alone?
- Do they have separation anxiety or medical needs?
- Will their food stay fresh and water clean?
Can You Leave a Cat Alone for a Weekend?
This is where it gets risky.
“Even if you leave out enough food, it doesn’t guarantee that your cat will pace themselves or that they won’t knock over their water bowl halfway through Saturday.”
— International Cat Care (iCatCare)
Some owners use automatic feeders and water fountains, but that doesn’t replace human observation. A cat could become unwell, injured, or simply stressed—and you'd have no way of knowing.
For weekends away, a check-in visit at least once per day is strongly recommended.
What About Kittens or Elderly Cats?
The rules change dramatically for:
- Kittens under 6 months – Need regular feeding, stimulation, and supervision. Should not be left alone longer than 4–6 hours.
- Senior cats or those with medical conditions – May need medication, softer foods, or monitoring. Should have daily in-person care.
“Older cats can become confused or dehydrated more quickly. If they stop eating or using the litter box, even for 12 hours, it can be dangerous.”
— Dr. Mikel Delgado, PhD, Certified Cat Behaviourist
Behavioural Effects of Loneliness
Even cats that seem independent can experience:
- Separation-related stress
- Over-grooming or toileting outside the litter box
- Depression-like withdrawal or hiding
A 2019 study in PLOS One showed that cats form attachment bonds to humans similar to dogs and infants. They may not show anxiety the same way, but they feel it.
“Cats are not solitary animals. They are selectively social. And they do notice when their person is gone.”
— University of Oregon, Department of Psychology
What’s the Safest Practice?
- Up to 24 hours: Fine for healthy adult cats if basic needs are met
- 24–48 hours: Should arrange a sitter to check in once or twice
- Over 48 hours: Daily care is essential; strongly consider in-home cat sitting
- Kittens, seniors, or medical: Never leave unattended overnight
Even one short daily visit can make a major difference in your cat’s wellbeing.
Don’t Just Feed—Check
An automatic feeder can keep your cat’s stomach full, but only a human can:
- Refill water if it spills
- Clean the litter box
- Spot signs of illness or stress
- Offer comfort and stimulation
