I know some people aren't going to like this, but let me tell the story. Little One is the only one of our six kitties that remembers the outdoors. All the other ones were found abandoned and were bottle fed. Harley and Monster didn't even have their eyes opened yet. Little One was a barn cat and was "catnapped" from the barn when she was around 4 months old. She was fine when she was a kitten, but now she doesn't interact with the other cats at all...unless you count growling and hissing. I honestly think she hates being inside...especially during warm weather. So, we've started letting her outside a little bit each day. Our house is at the end of a dirt road, so the only real traffic is us. She is spayed and still has her claws so if any of the barn cats mess with her she can defend herself. So far, she has mainly stayed on the front pourch, with a few little explorations to the back of the house, but she is a much happier cat! My problem is, I worry about her constantly while she is outside. I will NOT let her out at night, because she is mainly black and impossible to find but during the day she is free to roam. I want to hear from some other indoor/outdoor kitty parents and find out when do I stop worrying about her?
