I've had my Ball for almost a year, and he's been extremely agressive since the day I got him. I ordered him from a breeder in Oklahoma. He's eating well, and getting fat. He seems health in every way. I've NEVER even seen him in the "ball" thretened posture. If my hand goes into the cage, he rears back to strike. He has a seperate feeding enclosure. He's bitten me about five times, the last one was pretty bad, he latched onto my thumb, and wrapped around my wrist. It took me about 15 minutes to get him off (carefully). I'm not to concerned about holding him all the time, but it would be nice if I could hold him every once in awhile. Any ideas about how I could begin taming this fella? Thanks!
