If Ты let your cat out there is a good chance she could dissapear. It happens, though female Кошки do tend to stay closer to Главная than males. Most house cats, especialy if they're spoiled will behave еще dependant on human service than to rely on their instincts and hunt. They will hunt out doors, but in my experience they would drop the kill for a bowl of fresh canned cat food.
If there are a lot of other Кошки around, strays and such there's a good chance she'll get into fights, end up abused или pregnant (if not spade). If she is in heat she will likely stay out untill through mating, just keep an eye out if Ты notice her missing for a день или two, еще than three или four I'd check the local animal shelter in case anyone happened to pick her up assuming its a stray.
