Capped - White with an overlay of a different color.
Dalmatian - Like the dog! White with different size spots.
Dumbo - Named after the elephant. This rat has ears low on its head and looks like a clown.
Hairless - Nude, no hair. Often they are born with fur, but later lose it or have peach fuzz patches. They are particularly sensitive to cold.
Himalayan - Like the cat! Creamy white or ivory with darker brown on nose, rump and legs. Usually has pink or ruby eyes.
Hooded - A common lab rat color pattern. White with a different-colored hood and back stripe.

Rattus norvegicus
The Norway rat or brown rat. The majority of pet rats are of this species.

Silvered - Any solid color with an even mixture of silver or white hairs throughout the fur.
Tailless - Again, obvious. Difficult to breed for. Serious birth defects can result from the tailless gene. Also, since the tail helps with temperature regulation, they are much more susceptible to heatstroke.
