So I just got my bf a guitar for an anniversary present and he is not very good(of course he just started) but Cosmo really responds to it. Whenever he starts strumming Cosmo runs around his cage jumping around. At first I wasnt sure if he was enjoying it or if it was irritating him.Then I took him into the bathroom for playtime with the guitar because none of his play things have arrived yet. I just strummed on it and he started running around like crazy. This is only his third time out for playtime so far and this is the first time he ran around alot instead of hiding behind the toilet. He ran up to the guitar to investigate and then he jumped into the air and spinned! It was awsome. It is definately becoming a normal part of playtime:laughitup:
