Cats
In the Bengal breed,
tri-colour refers to a cat with black rosettes on a golden brown background. The centre of the
rosette is generally a darker version of the background colour, hence the cat has three colours:
pale background, black markings, dark rosette centre.
Tortoiseshell Bengal variants have occurred during breed development, but it is not an
accepted colour in a breed which aims to re-create a wild look.
ANOMALOUS TRI-COLOURS
A number of anomaous tricolours are discussed in "Mosaicism, Tortie Tomcats, Genetically
Impossible Kittens and Gender Anomalies". These include a white, black and grey tricolour
and a white, red and grey tricolour. A further unusual tricolour is best described as a "white
brindle".
The "white brindle" was one of the most striking "tortoiseshell" cats I have seen. Imagine a
brindled tortoiseshell in which all the black areas have been converted to white. The result
