Rat types and variety records
Rat types
There are no real rat breeds but we can find many varieties. Rats are usually described according to five main characteristics : base color, dilution, marking, hair type and ear type.
*The color (black, agouti, blue, etc.) and the dilution (if the rat is siamese for exemple) combine to determine the hair color on the body parts where the hair is not white. The color comes from pigments present or not in the hair whereas the dilution is a modification of the expression of those pigments as if the color was “faded”.
- The marking describes the white and colored hair distribution just as if a “stencil” would have been put on the body to hide the color on some parts.
- The hair type corresponds to the hair texture when touching it : smooth, curly (“rex” rats) or even naked.
- The ear type corresponds to the form, implantation and orientation of the ears. We only know two ear types: “standard” and “dumbo”.
To those five characteristics are added the eyes color (based on the previous criterions) and possible specifics such as dwarfism (“dwarf” rats) or tail-less rats (“manx” rats).
In the LORD register all these parameters are saved separately which means that some appellations does not exist such as the “ivory” type (refering to black-eyed albino rats) or the “wheaten burmese” type which designates a burmese agouti rat.

Variety records
Following the exemple of rats and ratteries, each rat type has its own record wether it’s a color, a dilution, a marking… These forms collect two types of information :
- Descriptive information such as the genotype, the standard if existing, the other denominations used abroad as well as pictures of rats carrying those characteristics;
- Statistics automatically calculated from rats forms including the frequency of this particularity within all the registered rats and the average longevity of those rats.

The writing of the description of each variety is still ongoing in coordination with the SRFA association. Thank you for your patience during the process.
