Well its good to hear that you want to give him a good home. A 3ft cage is WAY to small for such a big monitor. Thats ridiculous. I hate how people can be so ignorant. Anyways, ya just basically what JPShadow said. Just set up his cage and do not handle him, or have much interaction with him other than cleaning the cage, changing water, ect...After a few days, if you see him warming up to his surroundings, then slowly start interacting with him more and more. I just sit in my blackthroats cage and watch him. Hes very active and fun to watch. I let him roam my backyard all the time, and sometimes my house. But not my house anymore cause he took the biggest crap of a lifetime and it took forever to clean and get rid of the smell. But it was funny now that I look back at it. But ya, beautiful blackthroat you got there. Mine is 49 inches and 10 months old. Blackthroats are my favorite monitor. There very enjoyable. But if you have ANY questions, make sure you ask. What is your setup in your cage and temps and everything?
