Wanda, your enclosure sounds brilliant and well thought out, hopefully you'll have no escapes!
Herriotfan, are you actually in Saffron Walden? I know Saffron Walden a bit as I've worked there occasionally. I was thinking of going to the reptile place in Hardwick at the weekend, it's above the Petpaks store, but not run by petpaks themselves I don't think...used to go there a lot when I was younger, but only go to petpaks now for tropical fish food etc.
Have you had any luck with breeders round here? I'm willing to travel...when I know where they are!
