Thanks for all of the advice! I'm really worried about all of the dangers you guys mentioned, along with all of the worms and parasites that outdoor cats get xP... she really is very affectionate, but it can get to be over-the-top. She's also gained almost 10 lbs since we adopted her, because she's used to playing with other cats and being outdoors, and she has very little interest in all of the toys we have for her. So far, she's only gone into the backyard for about an hour while my Mom is out there and she has not left... I'm hoping it will stay that way!!
