Rat Varieties


Although I have only a few colors I am focusing on, I have had many other colors pop up in my breedings. This page is just a reference so people can see what each variety looks like. This is not an extensive list of all colors in existance - only the colors I have owned or bred! My descriptions may not match other websites exactly, but there can be a large difference in shades of certain colors, and on this page I am going by what I've experienced in my lines!

This page is a work in progress; over time other varieties will be added. Below each color name will be a description of the standard for rats of the color from one of several different rat clubs.

Rat Colors

Agouti-Based Color

Non-Agouti Based Color

Agouti is the "wild-type" color. Black is recessive to agouti, and these two colors are the "base" of all other rat colors. Every rat is either agouti or black, plus additional modifiers.

Russian Blue Berkshire Dumbo
Color to be similar to the blue mice or blue cats, a very dark slate blue color with dark ticking throughout. Eyes black.
Chocolate is a very uncommon color in the US. Chocolate is thought to be its own gene, although some think it may be a very dark shade of mink, but this has not been proven.

Chocolate Self Dumbo
A deep rich chocolate, as even as possible, devoid of dinginess and white hairs or patches. The feet to match top color. Eyes black.
Fawn and beige are red-eye dilutes (RED). This gene lightens the color of the eyes to ruby, and also affects the coat color.

Belly and throat to be cream. Feet to match top colour as close as possible, but a lighter shade acceptable. Eyes may be any shade of red to dark ruby but pink eyes undesirable. Slight heathering not to be faulted.
