If আপনি let your cat out there is a good chance she could dissapear. It happens, though female মার্জার do tend to stay closer to প্রথমপাতা than males. Most house cats, especialy if they're spoiled will behave আরো 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 মার্জার around, strays and such there's a good chance she'll get into fights, end up abused অথবা pregnant (if not spade). If she is in heat she will likely stay out untill through mating, just keep an eye out if আপনি notice her missing for a দিন অথবা two, আরো than three অথবা four I'd check the local animal shelter in case anyone happened to pick her up assuming its a stray.
