Fluffagrams thank you, this is all really helpful stuff, and I appreciate your help very much. Since this will be my first show, I didn't want to inadvertently do something wrong.
I'm going to go and have a look. I may come home with a new furry friend, or I may not, but I think it will be a nice thing to do regardless. I love hamsters and seeing them does help me remember the happy times, both with Mushu and previous hammies.
I will have to watch out for you and your hams
