[Nancy's Hamsters]

If the slate is formed into like a bowl with molded edges it would make a lovely cool perch. I know here in the states they make a slate, or fake marble bowl for reptiles which if turned upside down makes a wonderful cool spot for the hamsters, a bit pricey though. I use clay pots trays like you place under flower pots. They hold the cold rather long and the hamsters love just laying in them when it is really hot. The mice weren't thrilled with them at all.
