I recently caught a beautiful 4' Gopher snake and while we were building a nice "big" terrarium a smaller snake appeared.
We caught her? and after a short period she? escaped. She returned two more times and then we caught her again.
My question is: Can they be housed in the same cage? If they are both males, will they fight? How can a identify the gender?
Another question is: do they communicate? She seems to have known we were holding the other snake (her mate?).
