Personally, I prefer to keep our cat indoors permanently. The last time she got out, she came back in infested with fleas, which are horrible in FL. It took 3 months to get them under control. She isn't neutered, and I don't want kittens. She wants out, especially when she is in heat, but there are too many risks, feline leukemia, rabies, ticks, dogs, bigger warlike cats, you name it. I have seen indoor cats live 20+ years very happily. My outdoor or outdoor/indoor cats lived less than half that long, and I usually never knew what became of them.
