Since Dwarf hamsters in the hobby have no gene for long hair, this is a Syrians only month.  The Fur category accounts for 20 of the possible 100 show points.  The entire fur standard is reproduced below even though we won't be considering the shorthair coat.

"The fur shall be soft and very dense. Special attention shall be paid to the density of the belly fur. In Short Haired hamsters the fur shall be very short and even. In longhaired hamsters, allowance must be made for sex; i.e. males must have longer fur than females. Matting will be heavily penalised."

 

	These two males owned and bred by Lorraine Hill come very close to the ideal standard.
The hamster on the left still needs more length over the back and a little more thickness overall.  Selective breeding from this male resulted in the second hamster.  His fur thickness is ideal.  Further breeding would address increasing the length over the back.  (Reproduced with permission of Lorraine Hill.)

 

	For better or for worse, all the rest of the hamsters on this page are from The River Road Hamstery.  The male at left is a Satin Recessive Dappled Golden.  His coat is equally long over the back and sides.  Ideally, the fur should be 3" long which his does not approach.
	This Dark Eared White Satin male is "skirted."  The coat is long around the sides but uniformly shorter over the back.  This is regarded in some places as an acceptable variant of longhair, but in reality it is a defect and would be penalized for lack of both length and evenness.
	Even more of a problem is the male that just shows a few tufts on a coat that is barely more than a shorthair.  This Golden male has a "fluffy" coat more appropriate for a female longhair.
	This Satin Recessive Dappled Golden female is a sister to the first male.  Her coat is fluffy which is what it should be on a female.  Tufts on a female (usually on the rear and by the ears) are not penalized.
Fur density can be assessed by running a finger up a hamster's back from the tail towards the head .  As the fur parts, ideally, no skin should be visible.  Also, density should continue to the outer limits of the coat, providing it with fullness.  The entire coat should be free from sparse areas or bald spots.  Often, these are most apparent on the belly.  Fur thickness should be even throughout.  Even hamsters that ordinarily have good density may score poorly if they are in moult when the coat can get patchy.
	At the far left is the RD male from above.  His skin is barely visible where the fur is parted, indicating good density.  On the right is an elderly Satin Golden male whose fur has thinned substantially and lost all fullness.  Often, Satin coats will look thinner, but it should still be difficult to see through to the skin.
