I'm not sure, I think they come from South America. In Pennsylvania, you are basically going to have to provide warmth for your tortoises in the winter and a little bit in the spring and fall this can be done by having an indoor enclosure or a heated outdoor area, such as a heated night box or a shed. No matter what type of tortoise you get those are your options. I'm not totally familiar with Pennsylvania's climate but it sounds like you would probably get three full months of outdoor time, with a month or two here and there on either end of that. And there were obese six months of either indoor or heat needed. Smaller tortoises are easier to have indoors. If you are getting a hatchling then they will basically be indoors for the good part of a couple years anyway. You have to think of a backup in case the power goes out, especially with a baby. I am not being a wet blanket and I am just being realistic. Any tortoise can be kept anywhere if you have the money and know how to provide the correct environment. Think of where the tortoise came from naturally, that may help also. You can also look into box turtles, I think there are some that are native to Pennsylvania. I have a box turtle that I chose not to hibernate so she was inside all winter. For species that do hibernate, and if you choose to do it, you can hibernate them indoors as well. Do not do it the first year you have the animal and make sure you do lots of research here first.How do you all think a redfoot would handle PA conditions? I've read that as they get older they can handle some pretty cold temps.
