From an email:
I really like the cavy cages at your website! Here in Finland people are absolutely crazy about them at the moment - and the supermarkets probably wonder why they are selling lots of grid boxes nowadays ;-) Unfortunately they are available only in black so far...
In case you want the links for finland
the boxes are available at Citymarket in almost every city (
www.citymarket.fi ) and the plastic sheets you can buy from Etola Teollisuus. (
