For the record i am NOT talking about housing them together...rather hanging out together. I have a 6 inch ornate box turtle and my little baby sulcata and i have read that they cannot be around each other due to some microbe or something that they carry that will kill the other. but i cannot find out exactly how or what it is that is so bad for the other? i like to give them free time in the house and when it gets warmer in the yard...but i only have one house and yard so how can i keep it safe without keeping one caged up all the time(which of coarse would have to be the box turtle since she wont get as big as a small car lol)...is it something in their poop or what? i would love for them to meet and hang out together when my little guy (still cant decide on a dang name lol) gets a little bigger but only if it will not cause harm to either of them. can anyone tell me exactl what it is thats so bad and how it is transfered to the other, and what it does as well as how to prevent it from happening.
