**Adult Cats** Cats, unlike dogs, usually remain calm without people for several hours: they sleep, groom themselves, and play. For an adult cat accustomed to a routine, one night without its owner is generally not a problem. However, most veterinarians and behavior experts do not recommend leaving a cat completely alone for more than 24-48 hours, writes A-Z Animals. Behaviorist Mikel Delgado notes that cats are sensitive to changes, although they do not always show it. A long disruption of routine can cause anxiety, stress, or unusual behavior. Additionally, without a person, there is no one to notice and address problems: a water bowl may tip over, the litter box may become dirty, and the pet may fall ill. A cat's outward calm does not always mean it is not experiencing discomfort. Previously, we discussed why cats interrupt our work. **Kittens** For kittens, the limitations are stricter. A kitten under three months old should not be left alone for more than 20 minutes: it does not yet control its behavior and is particularly vulnerable to household dangers. From three months, a kitten can be left without its owner for up to six hours, and by eight months, for about half a day. Only closer to a year do most cats become capable of safely staying alone for a full day if they are accustomed to such periods. **If You Need to Leave for a Day or Two** - leave fresh water and a sufficient supply of food; - replace the litter in the box; - leave toys, beds, and access to high shelves; - place an item with your scent (a blanket or t-shirt) in an accessible spot; - remove hazardous items; - close off rooms that are off-limits; - eliminate access to toxic plants. However, even a carefully prepared apartment cannot replace a person. The most reliable way is to ask a friend or pet sitter to come every day. Such visits allow for checking the cat's health, maintaining its routine, and providing a sense of security. Cats value independence, but they need people much more than it sometimes seems.
