I will try it thank you.
I just have to admit that I might have already done things to hinder this behavior when he first got to me. I did not know aboit this idea then.
What I mean is he tried to get out of the enclosure by bumping his nose agains the glass and I did not let him out because I though this was escaping behaviour. After a few month he has mostly stopped wanting to come out. I am not sure I can make him be interested in coming out again but I can try at least.
