The Syrian hamster is the largest of the pet hamsters. It is normally between 15 to 20 cm long and can weigh between 150 to 200 grams. It is also the most common in pet shops and comes in various colours, patterns and hair types. If you watch the videos here you'll see a syrian hamster.
You can get short haired, long haired (it is only the males that can get the very long coats, the females stay fluffy), satin coated (this is a very shiny coat), Rex coated (the coat is slightly curly with the whiskers around the nose curling forward instead of sticking straight out) or combinations of these.
There are many colours commonly available including golden, cream, white, black, cinnamon, yellow, silver grey, dark grey, honey, sable etc. There are also other colours that might only be available from specialist breeders such as lilac, rust, smoke pearl, lilac pearl, silver black, melanistic yellow, dove etc.
In any of the above you can get a coloured hamster with white spots or a coloured hamster with a white band around it's middle. In some colours you can also get a tortoiseshell, which is a coloured hamster with 'yellow' patches and also a tortoiseshell and white which is a tri-coloured animal (as with cats tortoiseshells are all females).
As you can see there is a lot of choice when it comes to choosing your Syrian hamster!
