Can owning a cat improve your mental health?

If you've ever come home to a hard day and felt your shoulders drop the moment a cat wound round your ankles, you already know something researchers have spent the last decade trying to measure properly. The relationship between owning a cat and feeling mentally better isn't a myth invented by cat lovers to justify the food bill — but it isn't a simple, guaranteed prescription either. The honest picture, once you look past the headlines, is more interesting than either "cats will fix your mental health" or "there's no evidence at all".

This guide pulls together what UK charities, mental health organisations and peer-reviewed researchers actually say about cats and owner wellbeing, including where the evidence is strong, where it's mixed, and what that means if you're weighing up whether a cat is right for you.

What the evidence actually shows

The short version: cat owners consistently *report* feeling better for having a cat, but when scientists try to prove cats change mental health outcomes in a measurable, controlled way, the results are less clear-cut than the surveys suggest.

A 2022 systematic review published in *Social Psychiatry and Psychiatric Epidemiology*, which pooled 24 separate studies on pet ownership, loneliness and social isolation, found that "most of the studies did not reveal any differences between dogs, cats, and other kinds of pets" when it came to protecting people from loneliness. Cat ownership specifically wasn't linked to lower loneliness or isolation in the studies reviewed — a more cautious finding than owners' own accounts would suggest.

A separate 2025 meta-analysis in the *Annals of General Psychiatry*, covering 21 studies and more than 159,000 participants, went further: overall, pet ownership showed no significant link to reduced depression risk. Cat ownership specifically was associated with a small but statistically significant *increase* in depression risk (odds ratio 1.06), while dog ownership showed no significant link either way. The researchers suggested this may reflect cats' more independent nature compared with dogs — less built-in structure, fewer walks, and potentially added financial or caregiving stress that can offset the emotional upside.

None of this means cats are bad for you, or that the people who say their cat helps them are wrong. It means the picture is genuinely mixed at a population level, even though the lived experience for many individual owners is real and significant.

The Cats Protection survey: what UK cat owners say

Where the UK's own research is more one-sided is in owners' self-reported experience. Cats Protection, working with the Mental Health Foundation, surveyed 621 people and found that 87% of cat owners said their cat had a positive impact on their mental wellbeing, and 76% said they coped with everyday life much better because of their cat's company. Half of respondents said their cat's presence and companionship was the most helpful part; a third said stroking their cat was specifically calming.

A later Cats Protection survey, run for World Mental Health Day, found an even higher figure: 93.7% of cat owners said owning a cat helps their mental health, with 72% citing stroking their cat as most beneficial and 58% citing play. Around a quarter said the benefit was "very much" felt, rather than a small nicety.

"Sitting with a relaxed purring cat at the end of a hectic day is a soothing massage for the soul."

That's not a peer-reviewed claim, and self-reported survey data always has limits — people who already love their cat are more likely to say it helps them. But it's a consistent, repeated pattern across thousands of UK respondents over more than a decade, and it lines up with what many owners describe in their own words.

Why a cat's company can help

Even where the clinical evidence is cautious, there are plausible, well-documented reasons a cat's company can genuinely support day-to-day wellbeing.

Routine and responsibility

Caring for any pet builds a small, repeating structure into the day — feeding times, litter tray changes, a set play session. The Mental Health Foundation notes that this kind of routine and sense of purpose can be genuinely valuable, particularly for people managing low mood, ADHD, or periods where daily structure has broken down. A cat needing you gives the day a shape, even on difficult days.

Touch, purring and the stroking effect

Across every survey referenced here, stroking comes up as the single most cited benefit — ahead of play, company, or anything else. PDSA notes that just a few minutes of positive interaction with a pet each day is linked to lower levels of the stress hormone cortisol. Purring itself is often described anecdotally as soothing, and the repetitive, rhythmic nature of stroking a calm, relaxed cat is a genuinely restful physical action, distinct from screen time or other passive downtime.

Unconditional presence

A cat doesn't ask how your day was, judge a messy house, or need you to perform. For people managing anxiety, depression, or social exhaustion, that undemanding presence — company without conversation — is repeatedly cited as valuable in its own right, separate from any measurable clinical effect.

Where the research is more cautious

It's worth being honest about the limits, because oversimplifying the evidence doesn't help anyone deciding whether to get a cat.

• Cats are more independent than dogs. Several reviews note that cats show less social dependency and emotional responsiveness than dogs, which may partly explain why the loneliness-reduction effect is less consistent for cat owners than commonly assumed.
• A pet is a source of stress as well as comfort. Vet bills, worry when a cat is unwell, house moves, and behavioural problems all add pressure — and the 2025 meta-analysis specifically raised financial and caregiving burden as a possible reason cat ownership showed a small *increase* in depression risk in the pooled data.
• Correlation isn't causation. People who are already coping reasonably well may be more likely to take on a cat and stay committed to its care in the first place, which can inflate the apparent benefit in survey data.
• A cat is not a substitute for professional support. No charity or study reviewed here suggests a cat can treat clinical depression, anxiety disorders, or a mental health crisis. They're consistently framed as a support alongside proper care, not instead of it.

Cats vs dogs: is one better for your mental health?

If you're choosing between a cat and a dog specifically for wellbeing reasons, the honest answer is: it depends what you need. The 2022 loneliness review found dog ownership showed more consistent protective associations with social isolation than cat ownership, partly because dog walking naturally builds in exercise, routine, and chance encounters with other people. The 2025 depression meta-analysis found a similar pattern — dog ownership showed no negative association, while cat ownership showed a small negative one.

That doesn't make cats the "worse" choice. It reflects a different kind of relationship: lower-maintenance, less socially demanding, and often better suited to smaller homes, less mobile owners, or people who need calm, quiet company rather than an activity partner. If you're weighing this up seriously, our Pet Ownership Quiz is a useful starting point for matching your lifestyle, home and routine to the right kind of pet before you commit.

Reading your cat's side of the relationship

A cat's wellbeing and yours are connected — a stressed, unhappy cat is much less likely to be the calm, purring companion the surveys describe. Cats show affection differently to dogs, and it helps to know what you're looking for. A slow blink held while making eye contact is widely recognised as a sign of trust. Headbutting and cheek-rubbing mark you as part of their social group through scent. Kneading, a behaviour that starts in kittenhood, is associated with comfort and relaxation.

Equally, learn the signs that a cat is struggling, because a stressed cat won't deliver the calming benefits described above — for either of you. Cats Protection lists flattened ears, dilated pupils, excessive hiding, and changes to litter tray habits as key indicators, noting that "cats are subtle animals and it can be tricky to tell if you've got a stressed cat." Common triggers include house moves, building work, new pets in the home, and — perhaps counterintuitively — other cats in a multi-cat household, since cats are not naturally as socially flexible with each other as they are with people.

Is a cat the right fit for your mental health right now?

Before bringing a cat home for wellbeing reasons specifically, it's worth being realistic. A cat needs feeding twice a day, a clean litter tray, regular vet care including vaccinations and neutering, and years — often well over a decade — of commitment. PDSA's five welfare needs (a suitable environment, a suitable diet, the ability to behave normally, appropriate company, and protection from pain and disease) apply in full, regardless of how you're feeling on a given day. On the hardest days, that responsibility can feel like too much rather than a comfort — which is worth thinking through honestly before adopting, not after.

If you're not sure a cat suits your current circumstances, charities including Cats Protection, Blue Cross and RSPCA all offer fostering routes, which give you the companionship and some of the routine without a lifelong commitment while you find your feet.

When to see your vet

If your cat shows ongoing signs of stress — hiding, over-grooming, appetite changes, or toileting outside the litter tray — speak to your vet first to rule out a medical cause before assuming it's behavioural. Persistent stress in a cat can also affect the relationship you're relying on for comfort, so it's worth addressing early rather than waiting for it to settle on its own.

If you're finding your own mental health difficult, a cat's company can be a genuine support, but it isn't a substitute for professional help. If low mood, anxiety, or another mental health concern is affecting your daily life, speak to your GP or a mental health professional, alongside — not instead of — the comfort your cat provides.
