I'm thinking about getting a Russian tortoise , and I'm wondering how much space I need if I keep the Russian tortoise outside, and if I can keep a Russian tortoise outside in a suburbs of Maryland.
The bigger the better. Make sure there is always some shade and sun. Depending on your area, you might need a cover to keep predators out too.
It is possible to hibernate a russian outdoors there, but risky. I'd either hibernate indoors or just not hibernate and have a warm bright large indoor enclosure for winter.
4'x 3' or 6'x2' inside.
Hopefully outdoors you can set up a larger one; 10'x 4' or thereabouts? Make sure it gets sun April to September, and plant some bushes, or create a hide for shade.
