My Stinky cat (and Tank, while he was with us) is an indoor kitty. I wanted to keep them indoors because we live in an apartment complex, it's just not safe for them out there. I do let her out onto our patio (we live on the top floor), and there's really no way for them to get down unless they fall. Stinky actually did fall down, once. I came home from work at around 1 am, and heard a cat crying up in a tree right next to our kitchen window. I felt sad for it, but there wasn't anything I could do immediately for it. So I went inside, and Stinkpot is always right at the door waiting for me when I get home. Weird, only Tank was there. I searched the apartment, and realized it was her up in that tree. I woke up my boyfriend (he was thrilled), and he ended up climbing the tree, grabbing her, and bringing her down. At the time, she didn't really like him and was a little scared of him, so I was suprised she just let him grab her and bring her down. Perhaps she knew he was rescuing her? Anyhow, when we brought her in, Tank growled and hissed at her, but then we bathed her, and he chilled out. After that, she was quite traumatized for a while and wouldn't go out on the deck. Now she loves it out there again, but is very careful!
