I keep my Russian yearling inside 24/7 and I think he is thriving. I think with enough money and time you can keep small breeds 99% happy. I would love to have him outside but realistically we won't have a yard for awhile, and I waited many years to get a tortoise until I was more responsible, financially stable (money put aside for potential vet bills and the about $1,000 I spent so far on him and all his stuff and care), out of college and not moving around, new I could make a life-long commitment, etc. I know that Trevor would thrive even more outdoors, but with a MVB and a lot of space, etc, he is doing awesome. If he was outside I also wouldn't get to spend so much time with him. He gets attention each time we walk between the living room and kitchen. I do agree Sulcatas and other large breeds should never be indoor pets. I did a lot of thinking about the keeping a tort indoors thing and originally all the info out there made me put off my purchase for awhile, but then I saw some people on this forum and other places that do it and succeed, so I thought I'd try! Someday when I have a yard and live in a warm climate I'd love to provide a home for a Sulcata who needs one (I don't believe in supporting Sulcata breeders), but I fear that day will never come. I don't think I'd want the challenge of having to house them in a cooler climate, and I know they need a huge yard and many people underestimate that.
