You will notice the change in his behavior. He will be less threatened when you open the cage or come around. He may start to wait for you to open the door for food, drink in front of you, walk out of his cage, feed from your hand, etc.... you will know, but usually 2-8 weeks. Depends on the individual. Keep in mind, some chams like the rearranging and others don't. You will soon learn which you have. Most of mine, seem to like to be returned to same neighborhood. The males are the ones who seem to favor change, always looking for the next wife (to take 1/2 their stuff

)
