Let me give you a little bit of background.
Charlie was about 9-12 weeks when I adopted him from a place called Pets Without Parents (Columbus, Ohio). We brought him home and the first night, had him in his cage in the living room to sleep, although more barking/howling was done than sleeping. So, since a lot of people live in the house, after 2 nights of continual barking I decided he needed to sleep in a cage in my room. Some may say that wasn't smart but for reasons, it had to be done. He isn't scared of his cage or anything, he really likes it usually. The problem is he freaks out when no one is around. So, today I decided to purchase a cage for the living room because I don't feel that it is safe for him to be in the house roaming anymore... So, pretty much I realize my only option is to just make him get used to it but I want for it to be as painless as possible. That, I suppose, is what I need tips for.
(I'm going to put more oh his pictures on a site now for everyone!)
