I've recently got one of these cages for my hyperactive hamster Herbert. He loves it, though it took him a week or so to settle in. There's just a couple of things I've had to change that I thought I would let everyone know about!
Two problems:
Herbert's worked out how to unhook the metal dish that came with it, thus depositing his hamster food all over the shelf and making a noise!
He was rapidly gnawing his way out of the green
'Penthouse' that sits on the top of the cage. Another couple of days and he would have been out through the top door!
Somehow he *knew* there was a door on top and knew that it was an exit point. He hasn't attempted to gnaw the tubes at all and isn't really bar gnawing so it was a real escape-attempt not a boredom thing as far as I can tell!
What I have done to resolve them:
Herbert's food is now in a
bolt-on coop cup so he can't remove it. The dish is slightly bigger too so probably a bit heavier for him to shift.
I've removed the Penthouse altogether, he was destroying it and would have been out of the cage so I didn't have much choice really! He didn't seem to enjoy it anyway, all he did was try to escape from there. I've repositioned the tubes so that they still go up and around but now just go in a loop back into the cage. He still uses them and plays in them so I thought I may as well leave them in. Will take a pic of it to show what I mean just in case anyone else has a manic hamster.
Otherwise I like the cage very much. It was worth spending my over-time money on - I like the way Herbert can climb in it and I like the potential it has for hanging toys, adding leap n' ledges etc.
