Boulder seams great. I have a egyptian also, not as big as Boulder but I hope somebay he will be. He isn't as taim as Boulder, he dosn't really like me handeling him much. So I just let him do his thing not to disturbe his everyday life. You are pretty lucky.
:Here is a movie of Boulder exploring the backyard. We are doing some yardwork and one of the fences is down. The rest is explained in the title. Enjoy!
