Whats a good tortoise to have in WI?

It's been a long time since I posted on Fauna! But I thought I could turn to all of your collective minds with a simple question.

I want a tortoise but I don't want a big one or one that is going to be high maintenance.

I don't really feel comfortable in my neighborhood having an outdoor enclosure since we have a lot of racoons and foxes and random dogs around here. That and my old neighbors will start gossiping about me and my wierd pets.

So it's gonna need to be indoor friendly. I have a relatively dry house. I don't have the room for a huge tortoise table but I could make a decent sized enclosure in my back room for the little guy.

I don't want to have to grow grass in the winter as my cats will do their "business" in it and dig around and pretty much make a big mess. Mmm pee grass!

I've had an Indian Star but she got sick and passed away from a sinus/cold/respitory type infection. That was pretty traumatic! It's been almost two years since then and I am a bit more wiser and prepared.

Some others have sugguested cherry foots, but I don't know a whole lot about them. I worry about humidity concerns...

So northlanders let me know what you've done in the past and what has worked for you.
