My female (Sasha-6") has been trying to mount my male (Theo-4.75") for the past couple months. Theo has shown no interest and is not aggressive at all. Sasha is constantly finding him in his hide and tries to ram him out. A couple weeks ago, I caught her digging a test nest and noticed that for the next week or so, she was pacing, climbing, smelling things, tapping her nose on the walls, etc. She was showing all the signs of being gravid, but now, she has calmed down and is just constantly trying to mount Theo when she sees him. No eggs have been found. We have had Theo one year, and Sasha about 8 months. I'm not sure how old they are. Is this normal for a female? Should I separate them? Is Theo mature if he is under 5"?
