I want to start target training Java so he doesn't become bored, and to establish trust, but I'm not sure where to start. Lately he's been very nippy and a little crabby, but I want to try to enrich his life without pushing him out of his comfort zone. He has plenty of toys but I can tell they are still foreign to him, he'll knock them around for a few minutes but he mostly spends his time stationary. I would like advice on ways to enrich his time until he's comfortable enough to leave the cage. I keep television on for him and I'm always in the same room with him so he has plenty of socialization. What can I do?
