Silver Grey is the best know and most bred of the silver ticked varieties. It is genetically a black mouse with silver ticking. Earlier on in the mouse fancy this variety was recognized in three different shades (light, medium, dark), but the current standard calls for the darkest version.
Best Silver Greys tend to grown from youngster looking like black mice at first, then growing an even silver ticking after their first molt. Those pups who have ticking from the first coat on tend to turn too light, with their uncercoat turning often white on their bellies and flanks.
Biggest challenges are usually connected to too little ticking or light undercolour. The standard calls for bluish black undercolour, but the silver gene alone can bleach the undercolour too much. In addition to this, some other factors may contribute towards a lighter hair roots.
In order to keep the undercolour from suffering, one should keep Silver Greys and Pearls as strictly separate strains. Silver Grey lines should also be kept clean of chocolate dilution. One of the common faults of this variety is unticked extremities.
Silver Greys have traditionally been bred in short hair, but the variety is very charming in satin. The satin sheen lifts up the silver ticking and makes the mouse downright sparkle. This is due to the satin having a stronger effect on lighter hair, when compared to darker.
