pretty cool huh? You get to see behavior you dont see indoors.
He may be stressed out a bit cuz its new but they get used to it and expect it. Dont be surprised if he gets more aggressive outside and really doenst want to come in. give him something to hide in or under while out. Next spring plant some red Hibiscus and you are set! Being able to get them outside is a privilege, I think.
