It depends. If you mean several hours a day, sure, kitty will be just fine. If you mean a few days in a row, kitty will be fine, too. Just make sure she has enough food and water. It would probably be a good idea to prepare a couple of additional litter boxes for her, too. But if you're talking several days, then you have to make sure you have the right type of food and water dispensers. That's the nice thing about cats; they can be pretty independent. One thing though, cats get lonely. That's why you should have at least two cats. They keep each other company when you're not there.

Whenever I go away, I have someone check in on my cats to feed them daily and clean their litter boxes daily.
