Since most cats sleep 13 to 18 hours a day, leaving them home alone while you're at work is usually no problem. However, if you have a kitten, an elderly cat or a cat who was recently adopted, there are some additional precautions you should consider. How long can your kitty safely be left on her own? If you're leaving a cat home alone, here are a few things to keep in mind to ensure that your pet stays physically and emotionally healthy.

How Long Is Too Long?

How long you can leave a cat home alone really depends on the individual cat and your relationship with your feline friend. If you've just adopted a new kitty, she will need time with you at home to learn your schedule, get into a daily routine and know what behaviors are appropriate in your home. PAWS notes that you should supervise any interactions with other household pets during the first few weeks with a new cat to make sure your fur family is adjusting to the addition. The first few weeks are also a crucial time for you and your cat to bond and develop a relationship.

Cats who have been in your household for a few months or years may be perfectly happy home alone for 8 or 10 hours, but they may also become bored, lonely or stressed. Keep an eye out for signs like overgrooming or going to the bathroom outside the litter box, and talk with your veterinarian if your cat's eating or litter box habits change.

Cats need a steady supply of food and fresh water just like any animal, so any pet left alone will need access to both, as well as a clean litter box. In addition to these basics, your kitty will appreciate safe ways to amuse herself like jingle toys, a cat tree to perch on or even a rustling paper bag.

Looking Out for Kittens and Senior Cats

Age plays into how long you should be leaving a cat home alone as well. Kittens are curious creatures, and they can endanger themselves by scratching, pawing or eating dangerous objects like wobbly vases or poisonous houseplants. The Nest recommends kitten-proofing one room and equipping it with a litter box, food, toys and fresh water if you need to leave young cats unsupervised.

If your kitten has to be alone for more than 12 hours, it's best to find someone to stop by and check on her. Have that person check on your pet's food and give her fresh water. If your cat has access to multiple rooms, your cat sitter should also walk around your house and make sure your kitten hasn't gotten stuck in any small spaces or closed herself in a room or closet.

Although older cats may be less likely to get into mischief, they may struggle more with environmental factors. If you're leaving your cat alone during hot summer days, make sure she has a cool place to nap and can access several bowls of water in different spots around your home while you're gone. Since older cats are more susceptible to illness, find a pet sitter who can stop by at least once a day if you're going to be away for too long.
