Thanks KatiePillow, I am all for upgrading the cage, apart from I don't know of any others that have the aquarium case and only a few bars (which I prefer) I'm all for any suggestions, but just not one with bars (or only a few bars) - I had a bad experience with bars with my previous hamster, as well as with my friend's one, both ending in tears
I do have space for a very large cage, but I'd like to keep it small as my mum isn't too keen on the idea, and I don't want to put her off further.
Thanks again guys!
