My cats are and always will be ... INDOOR ONLY.
I totally agree with Jen's reasons..

I want my cats to live long, healthy, happy lives, and I feel the only way I can do this, is to keep them inside, and If I ever DO get the room to let them out, that would ONLY be considered with them on a leash and me RIGHT there watching where they sniff...

people are cruel, and I will do what I can to prevent their cruelty from coming to my babies.

There are too many more dangers outside to warrant me letting my babies go out there. They will just have to be happy with a screen window / screened in porch.

I used to live in the country and we had a barn, with barn cats that came with it... I don't think any but ONE was seen around more than 2 yrs max.. and the one that was seen, was because she got used to us, and we took her inside, where she happily adjusted to life as an indoor baby!

but its just my opinions on the matter.
