The Mottled pattern mutation occurred in the UK in 1991 and a variable amount of white patches, spots, bands, collars on the body with the belly being pure white.

The amount of white varies immensely with some Mottleds have only one white spot on the side or back, whilst others have a white collar or band or large patches of white, to white all over with a very small spot of colour. The patterns the mutation causes are highly variable.

The Mottled can be combined with any colour or coat type so it is possible to produce Opal Mottled, Argente Mottled Satin, etc.
