How is Robbie doing? Isn't funny how they all knew something wasnot right and stayed closed by in case they were need to help. Sound like he may be doing better. Keep a close eye on him. Maybe you can call the vet in the morning and just let them know what happen and see what they say. If he is up and walking and jumping I don't think it is broke. It would be awful pain to walk and jump if it is broke don't you think. Keep me posted
