Hi Debs (talesoftheriverbank - wow Debbie seems to be a popular names for hamster owners!)
Its ok thankyou, I went out and bought Toby his own ball yesterday! He tried it out last night and was quite good at it! Was far to interested in Hazel's cage though, will definitely have to keep an eye on him
I'm going to use the old ball without a lid in my rats' cage, try and cable tie it to the wall as a little cubby hole for them, see what they make of it.
