I recently bought two new dwarf hamsters as my darling Campbell's dwarf Gråperle (also known as Pearl to some) died of old age in December 08. However, I ended up with Roborovskis this time around. Two females from the same litter, they were supposed to get along well and to keep each other company. Of course no such thing happened and I had to buy an extra cage within the first few weeks.
The two fighting females are called Knerten and Fjerten, and this blog is about them. The Incredible Invisible Dwarf Hamsters. Let's see how this goes.
