Yesterday I took Monty outside and let him climb in the tree for a while. He had a wonderful time and he can move quite fast when he wants to, so I never let him get out of my sight or too high in the tree!
Thanks everyone - I have had him for exactly 10 months today! Every month around this date I have taken a photo of him sat on my finger to chart his growth! Once he gets to a year old (on 3rd September) I will post them all in one thread!
