When I separated my male from my females, he hasn't been social with me. When ever I approach his cage he runs away into his little house. I tried to prompt him out with treats. Even though my girls love the treats he will not go near them or ever seemed to be bothered. He seems healthy. He always runs on the wheel and climbs up the bars. His coat is also very healthy looking. But he won't go near me. I don't want him to feel alone and I don't want to feel like I'm a predator or like I'm socially neglecting him. So how do I win his trust? Please help me.
