It's not something most cat owners think about until they notice their older cat acting a bit out of character. Maybe they're yowling at 3am, getting confused in their own house, or missing the litter tray when it's right beside them. Cats can experience cognitive changes as they age, in much the same way people can, and the signs are easy to miss because they often look like a cat just slowing down with age.
This is a friendly starter guide to feline cognitive dysfunction (FCD), or cat dementia, in plain English. What it is, what to look out for, and what you can do to help your senior cat feel comfortable and settled. It's an introduction rather than a deep medical dive. If anything sounds familiar, your clinic is the best next stop.
Quick answer
Yes, cats can get a form of dementia. It's called feline cognitive dysfunction (FCD) and it's a gradual change some older cats experience in how their brain works. Common signs include night-time yowling, disorientation, changes in litter tray habits and altered sleep patterns. It's most often seen in older cats. It can't be reversed, but it can often be supported with the right routine, diet and home set-up. Worth chatting to your clinic if you're noticing changes.
What Is Feline Cognitive Dysfunction?
Feline cognitive dysfunction, often shortened to FCD, is the everyday term for the gradual changes some older cats experience in how their brain works. It's similar in some ways to dementia in people. Memory can shift, sleep patterns can flip, recognition can fade, and cats can become a little more anxious or confused.
It's gradual, usually unfolding over months or years rather than appearing all at once. Some cats show only mild changes, while others develop more noticeable behaviour shifts that benefit from extra support at home.
How Common Is It?
More common than many cat owners realise. The chances tend to go up with age, and it's most often noticed in older and senior cats. Plenty of senior cats never show meaningful signs at all, while others develop changes worth recognising and supporting early.
Cats are also masters of hiding when something is off. That makes early signs easy to miss, and many owners only notice once the changes have been there for a while. The good news: spotting it earlier means more options for support.
Signs to Look Out For
Cognitive change in cats often shows up in a cluster of small behaviour shifts rather than one obvious moment. The classic signs spell out the acronym DISHA, which is a helpful way to remember what to watch for:
D for Disorientation
Getting lost in the house, staring at walls, missing the litter tray when it's right there, or seeming confused in rooms they've lived in for years.
I for Interaction changes
Less interested in cuddles or play, less interested in greeting you, or the opposite, becoming a lot clingier than they used to be.
S for Sleep cycle changes
Sleeping more during the day, restless or vocal at night, waking up disoriented, or yowling in the early hours. A flipped sleep schedule is one of the most commonly noticed signs.
H for House-soiling
New accidents outside the litter tray, going right beside it, or forgetting where the tray is. This is one of the most distressing signs for owners and pets.
A for Activity changes
Less interested in usual play or hunting games, more pacing or wandering aimlessly, or repetitive behaviours like circling.
And: Anxiety
Easily startled, vocalising more, hiding more often, or seeming uneasy about things they used to take in their stride.
One sign on its own often doesn't mean much. Two or more together is what's worth flagging.
What Causes Cat Dementia?
The simple answer: ageing. As cats grow older, the brain goes through gradual changes. For some cats, those changes start to affect everyday navigation, memory and behaviour. The exact reasons aren't fully understood, but age is the biggest factor.
It's worth knowing that other things can look like cognitive change in older cats, including:
- Vision or hearing loss
- Joint pain or arthritis
- Thyroid changes
- Kidney changes
- High blood pressure
- Anxiety or stress
This is why a chat with your clinic matters if you're noticing changes. Some of these are very treatable, and getting the right diagnosis means you can address the right thing.
What You Can Do at Home
Cognitive change can't be reversed, but there's plenty you can do to help your cat feel safer and more settled. The aim is to keep their world predictable, calm and easy to navigate.
Keep routines steady
Same wake time, meal times, play times. Routine reduces anxiety and gives your cat clear anchors to rely on.
Don't move things around
Keep furniture, beds, food bowls and litter trays in the same spots. Familiar layouts make a big difference for a confused cat.
Multiple litter trays
Having one tray on each level of your home, or one in each main area, helps an older cat avoid accidents when they can't quite remember the way.
Easy-access food and water
Make sure food and water are easy to find and reach without jumping. A water fountain often gets older cats drinking more.
Soft, warm sleep spot
A cosy familiar bed in a quiet room helps them settle. Older cats feel the cold more, so warmth is welcome.
Nightlights
Low-watt nightlights along key paths help cats with fading vision navigate at night without bumping into things.
Calming pheromones
A pheromone diffuser can help anxious or unsettled senior cats feel more secure. Plug one in near where they sleep.
Gentle daily enrichment
5 to 10 minutes of easy puzzle play, food foraging or wand games keeps the brain engaged. Keep it simple and rewarding.
Senior-appropriate diet
Some senior cat diets include antioxidants and omega-3s to support brain health as cats age. Worth chatting to your clinic about a transition.
Foods and Supplements That May Help
Some senior cat diets and supplements are formulated to support brain and overall wellbeing in older cats. They're not a fix on their own, but they can be a useful piece of a wider plan. Always check with your clinic before changing diet or adding supplements.
Calming Aids That May Help
Cognitive change often comes with anxiety, especially around night-time. Calming products may help your cat feel more settled.
Easy Enrichment Ideas for Senior Cats
Mental engagement helps older cats stay sharper. Keep sessions short, easy and rewarding. Floor-based and stationary activities are kinder on senior joints than anything that needs jumping or climbing.
When to Get a Check-Up
Reach out to your clinic if you're noticing:
- Two or more cognitive change signs together
- New or worsening confusion at home
- Sudden changes in behaviour, sleep or toileting
- Yowling at night that wasn't happening before
- Drinking noticeably more or less water than usual
- Weight loss despite a good appetite
- Stiffness, hesitation or signs of pain alongside
Your clinic can help work out whether something else is going on (like thyroid or kidney changes), rule out other causes, and put together a plan that works for your cat. The earlier you get a check, the more options you have.
Frequently Asked Questions
Can cats really get dementia?
Yes. Cats can experience cognitive changes as they age, similar in some ways to dementia in people. The proper name is feline cognitive dysfunction (FCD). It's most often seen in older and senior cats.
What are the first signs of dementia in a cat?
Early signs are often subtle: a flipped sleep schedule, mild disorientation in familiar places, changes in litter tray habits, less interest in greeting you, or new night-time vocalising. They can be easy to miss because they look like just slowing down with age.
At what age do cats get dementia?
It's most often noticed in older and senior cats. Some show signs earlier, others never show meaningful signs at all. If your cat is in their senior years and showing changes, it's worth mentioning at their next check-up.
Is feline cognitive dysfunction painful?
Cognitive change itself isn't typically painful, but it can cause anxiety and confusion that's stressful for your cat. Other age-related conditions like arthritis or dental disease can show up alongside, and your clinic can help spot and manage those.
Can FCD be cured?
It can't be reversed, but it can often be supported. A combination of senior-appropriate diet, calming aids, mental enrichment, predictable routine and (in some cases) options recommended by your clinic can all make a real difference to how your cat feels.
How long do cats live with dementia?
It varies a lot. Many cats live happily for years with cognitive change once they have the right home set-up and routine. The progression is gradual, and quality of life is often very good with the right support.
Why is my old cat yowling at night?
Night-time yowling is one of the most common signs of cognitive change in older cats. It can also be caused by anxiety, fading senses, hunger or an underlying health issue like thyroid or kidney changes. Worth getting checked, since some causes are treatable.
What food helps cats with dementia?
Senior-appropriate diets that include antioxidants and omega-3s are popular for supporting brain health in older cats. The right food depends on your cat's age, weight and other health needs, so it's worth chatting to your clinic.
