I've seen this cage a few times on Amazon.de - but they don't ship to the Uk - however it's available on ebay
Called the Ricardo, but it is basically a Barney but with an extra shelf! So if anyone is thinking an extra shelf might be useful and might be getting a Barney, it could be an option. It doesn't come with the house that usually comes with the Barney though but houses are easier to get hold of than shelves!
