I ended up buying a 48" off ebay for £33 so not too bad i thought the bigger the better as i still dont know how big she is going to get her dad weighed 16lbs and her mum 19lbs so i suppose shes going to get pretty big! I cant wait hehe! She is still being litter trained so at the moment she spends half an hour in the cage half an hour out just until she learns to go back to her cage when she needs to do her buiness although she is pretty good and learning quickly!! I find it a lot easier to litter train younger buns!!
