How long can you leave a kitten alone? Our guide

Many new kitten owners reach a point where they'll have to leave their growing cat alone. Whether for work or a class, it's not always possible to bring our fabulous feline everywhere we go.

But you need to do it at the right time, in the right environment, with a kitten that feels comfortable alone. It's essential to take supervision, socialisation and safety seriously.

It largely depends on their age, environment and temperament. Below, we'll answer the question of "how long can you leave a kitten alone?", if you can leave a kitten home alone and share safety and training tips.

Can you leave a kitten home alone?

It depends. You can leave kittens alone after a certain age, but it's generally recommended to limit their alone time when they're under four months old.

The top-level advice is to gradually increase the time they spend alone while making sure they are safe and have everything they need, like a litter box, food, toys, training and water.

There aren't many hard rules after four months; it depends on your kitten. But there are are some factors you'll need to consider when asking yourself "can I leave my kitten home alone?"

Factors to consider

Age

Young kittens will need more (or constant) supervision. This is the main factor when deciding if a kitten should be left alone - are they old enough?

Food and hydration needs

Very young kittens have urgent food and hydration needs, which is one of the reasons why they can't be left alone.

As cats age, their ability to self-regulate their food and water use improves, and they'll generally need less frequent meals, meaning they can stay home alone longer.

Health conditions

Kittens and cats with health conditions may not be able to be left alone for long due to their need for medication or treatment.

Litter training and safety concerns

Some kittens struggle with litter training or general safety training, which will limit the amount of time they can spend alone. This factor, however, is treatable with the right cat training regime.

Socialisation

You and other cats will need to spend lots of time with younger kittens to make sure they're socialised properly. This need reduces as they age, but poor socialisation can lead to long-term behavioural problems like separation anxiety.

Your home

Some homes aren't suited to leaving kittens and cats alone for hours. It is possible to kitten-proof a home, but some homes can struggle with it.

Our guide onkitten-proofing a home explains more, but generally, kitten-proofing involves:

• Checking appliances

• Clearing shelves and tables

• Closing doors and windows

• Keeping plants out of reach

• Managing wires and electrical devices

• Securing blinds and curtains

• Securing hazardous products

How long can a kitten be left alone by age?

Newborn to four-weeks-old

Kittens of this age shouldn't be left alone; they need constant care. Young kittens need feeding every two or three hours if bottle-fed, and they need careful supervision.

Four to eight-weeks-old

We don't advise leaving kittens of this age alone. But if you have to, you should only do it for around an hour max.

At this age, kittens are still learning how to regulate body temperature, eat solid food and look after themselves, so the risks are high.

Eight to 12-weeks-old

So, how long can you leave a two-month-old kitten alone?

You can leave kittens of this age alone for around two to four hours. But remember they still need frequent meals and supervised playtime.

Three to six-months-old

Kittens at this age should be gaining confidence and self-assurance quickly, so they can be left alone for around four to six hours. Things tend to be more flexible and hard to pin down at this age, as kittens will vary depending on their routine and temperament.

Six months and older

Cats that are six months and older can be left alone for eight hours or more, provided they have food, water and a safe environment.

Sometimes, though, cats can suffer from separation anxiety, which we've covered in detail in ourseparation anxiety in cats guide.

Tips for leaving your kitten home alone safely

Consider a pet camera

Pet cameras allow you to monitor your cat from your phone. But do note that some kittens and cats become anxious around these, so don't use one if it causes your cat stress.

Have a back-up plan

Having a friend, neighbour or professional pet sitter to check in on your cat can be a big help, especially if you're away for a while.

Provide interactive entertainment

Cats can get a bit bored and lonely, even if they're cool and collected on the outside. Having things like interactive toys, scratching posts, and window perches can keep your kitty entertained while you're gone. Be sure to only leave them alone with toys that are safe and don’t require supervision.

Set up a safe space

Sometimes, kitten-proofing your whole home isn't possible. But having a kitten-proofed room or "safe space" is possible for most of us. This will have things like food, litter, toys and water. It'll also give your kitten some space to chill.

Use timed feeders

Timed feeders are helpful for some cats as they provide meals at regular intervals, even when you're not in the house.

How to assess your kitten's comfort level with being alone

You should leave your kitten alone and quietly observe them to see how they're doing. Return if you hear them becoming too distressed, but try to hide and see how they're doing.

Gradually increase the amount of time they're alone and assess how they react.

Signs they're comfortable

Engagement with toys or play

A kitten engaging with the things it normally does, like exploring, playing or using toys, usually means they're comfortable alone.

Little vocalisation

Too much vocalisation is a key indicator of discomfort, so if your kitten isn't making too much noise, it's a good sign they're okay.

Normal eating and drinking

Following their regular eating or drinking habits is a key sign they're all good.

Relaxed behaviour

Relaxed behaviour, like sleeping or self-grooming, means they're likely okay too.

Signs they're uncomfortable

Body language

A discomforted cat will exhibit signs like:

• Flattened ears

• Hiding

• Hunched posture

• A tucked tail

• A tense, trembling body

• Squinted, glassy eyes

Clinginess

This happens when you return. If your kitten is overly clingy when you come back from being away, it can indicate they've not had a good time alone.

Destructive behaviour

Scratching furniture, chewing or other destructive behaviour indicates anxiety or stress.

Excessive vocalisation

Excessive vocalisation is a key sign that your kitten is uncomfortable.

Hiding

A kitten can hide when it's anxious or scared, so if your kitten suddenly hides while you're gone and takes a while to come out when you return, it can indicate discomfort.

Our kitten hiding guide explains more.

Irregular eating or drinking

Strange eating or drinking habits - like eating far too much, eating too quickly or too little - can indicate anxiety or stress.

Litter box frustrations

Anxiety or stress can sometimes manifest as your kitten refusing to use their litterbox and going to the toilet elsewhere.

Overgrooming

Grooming too much to the point where it's causing damage or pain is a self-soothing behaviour and can indicate anxiety.

Pet care options

There are some options if your cat struggles with being alone. For example, if you work long hours, you can look into professional pet care or work in a routine where you can visit home more often.

Similarly, some kittens benefit from a second cat as a companion. This can help prevent "single kitten syndrome", where some solo cats experience intense loneliness. Just make sure you introduce them to each other properly first!

If you're going on holiday and leaving your cat behind, catteries can help.

Emergency preparedness

You should prepare for emergencies if you're away for a while.

We recommend getting rid of potential environmental hazards in your home, like electrical hazards, poisonous plants and toxic substances.

How kitten insurance helps

To recap: how long you can leave your kitten alone is firstly defined by age. Leaving young kittens alone is dangerous. After that, it's all about your kitten's personality and needs; it varies on a kitty-by-kitty basis.

Remember to always monitor your kitten's behaviour and adjust accordingly. Your kitten's needs will change throughout its life, so being vigilant always pays off.

And kitten insurance can help you stay prepared for unexpected health issues, giving you and your kitten a safety net.
