Wolverine is a little cutie
The Hamster heaven is really expensive, you can sometimes get them on ebay but not often.
There is the Alaska on zooplus.co.uk and that's only £35 with 10% off your order if you've not shopped with them before, and free delivery over £19.
They have great toys on there and decent wheels too, all really good prices.
There is also the Barney on zooplus, that's £60 right now but does often go down in price.
Zooplus change their prices on cages ALL the time!
There is also the Mamble cage on littlepetwarehouse at just £35 as well.
