Dwarf hamsters are the most common type of hamster that were adopted as pet. They are cute, easy to care and most importantly they are funny. Their act and behavior will surely make you smile or even laugh. They move fast and playing at most of their time. One of my dwarf hamster always run in a small circle at full speed for a minute and then stop for a while for a break lying on it's back with all legs up and then coutinue running like mad scattering away the beddings.
Usually, dwarf hamsters are 2.5-4" long and weigh 1-3 oz. on average. They have stubby little furry tails and fur on both the tops and bottoms of their feet. There are many different colors and patterns. They're sometimes called "Siberian dwarfs," but this is a common pet-store misnomer. They're also called things like "fancy dwarf hamsters," "blueberry hamsters," "blackberry hamsters" and other cutesy, inaccurate names.
The Campbell’s breed by large commercial breeders have given the dwarfs a bad reputation as being Nippy biters. This is not so as most Campbell’s are friendly inquisitive little animals that like to be held. The biting trait is I believe inherited. And by carefully selecting only animals that don't bite I have breed this trait out of my Campbell’s. I do have several females that will nip if they have babies. But that is to be expected of any animal with babies.
