Hi fellow wisemen/women! :)

I can't live without a pet, I just moved and I need a pet, I am alone most of the time and I think it would be nice to have one...

I need one that's low-maintenance, since I go to work on constantly shifting schedules, and I stay at work at around 10 hours a day (including transportation, traffic, agh), nut I have 2 days of weekly, and I also feel like I can't have something boring... I'd like my pet to be pretty interactive but not too needy (e.g, I'd love a dog but he might not like the lack of attention).
I don't mind if the food and housing is a bit expensive, as long as I don't have to clean it too often. (Am I even being reasonable?? )

My place is pretty small, no lawn, just garage with a gate, not like those shutters... Sort of open?. If I can keep my pet indoors that would be great.

Thanks for the help anyone!
I'm wiling to adjust these things a bit just to get a good companion :)
