None of them like the outside (except for Moo, my cat/dog ) so it's not a problem for me.
I am glad your cats are happy and content inside, I bet your cats were raised inside. It makes sense that a cat raised indoors, would never get into the habit of being outside. Except your cat/dog (Didn't you post some pictures of that cutie recently?) And I agree that indoor cats are certainly safer cats.

Why would they want to go outside, they have hooman slaves running around the house for them all day. lol

I understand why people keep cats indoors in USA and other cat unfriendly places. (Busy roads etc). And I understand Soledad has the difficult challenge ahead of making an inside/outdoor cat indoors only (Best wishes to Boo, may it be an easy transition for you)

If I wanted to keep cats in doors, I would raise kittens indoors but I could not dream of taking adult strays and trying to keep them indoors forever. It was hard enough keeping George inside for a month.

Ps. Although I do like the idea of those fence topper things (I think Noah'sMommy posted a link to). I wouldn't mind restricting my cats to our back garden. So this is a possibility, when we remove the hedges and put fencing up.

PPS. I think this might be another English thing ! Hedges around gardens which allow free traffic of all local cats though all neighbouring gardens. Our garden is very popular (sigh) as it is usually empty of people/kids. Though when Milly & Milo start going out they will probually keep other cats out of our garden.
