I had to move Sadie into the other room. Sadie and Draco grew up together. I joined the forum here and learned they needed to be in their own enclosures. At first they were side by side. Then I had to put a screen so they couldnt see eachother. Then one day Draco mounted her when I had them both out at the same time. And he began head bobbing every time I got him out when he saw her in her enclosure so I put her enclosure across the room from her. It was not far enough. He then began to run at the glass hitting it pretty hard on a regular basis to try and get to her. He was hitting it HARD! Finally I just put her in a different room. She is now in her permanent enclosure so that is a good thing. I swear he is looking for her when I get him out now...
