My little girl strictly stays indoors. But, that's b/c I have had HORRIBLE luck with letting my kitties outdoors in the past. Between the cars, the diseases and the fighting with other cats, I've unfortunately lost quite a few kitties that way.
Ocassionally I will allow her to come out on the deck with me, but she can't go further than a couple feet from me b/c it's 'fensed in.' My only concern is that I know she might start to REALLY LIKE it and start "craving" it to where she is crying to go out. I've had that issue come up in the past with cats...thinking, "ok, I'll just let him/her out here and there only on a lease or with me there ONLY," only to have the kitty trying to dart out the door now every time it opens b/c he/she is so desperate to get out....once they get that little taste of the outdoor regardless in what form it is, it just seems like it's SOOO difficult to get them to 'be happy' indoors after that point, you know?
I would like to try her on a lease but it still scares me that I will run across this issue....
