white Cat with tan pattern ; but I have also never 

 seen what would be regarded as a pure albino 

 Cat ; that is to say, a white Cat with pink eyes. 

 White Cats often, however, have blue eyes. This is 

 a sign apparently of incomplete albinism, if we may 

 judge from the fact that blue or bluish eyes occur 

 not uncommonly in white or partly white horses and 

 dogs, especially sheep-dogs, and typically accompany 

 pale complexion and blonde hair in mankmd. A very 

 distinct and remarkable albinistic breed of Cats is 

 the Siamese. The newly-born kittens are pure white, 

 and the eyes are frequently blue ; but as age advances 

 the Cat gradually turns brown, the head, legs, and 

 tail becoming first of all suffused with dark pigment, 

 and this later in life extends more or less over the 

 body as well. This change from the albinistic to 

 the melanistic phase is comparable to the change from 

 the reddish to the blackish-grey phase in the West 

 African tiger cat above mentioned. Faint spots, 

 however, may often be seen on Siamese Cats, betraying 

 the descent of this breed from a " tabby." It may 

 here be explained that the eyes of Cats differ in 

 colour, but not to the same extent as the coat. 

 Green is the normal tint ; but just as albinistic 

 cats resemble blonde human beings in often having 

 blue eyes, so do red Cats often resemble red-haired 

 men in having red, or as fanciers call it " amber," 

 eyes. Amber eyes are also considered by fanciers a 

 sign of good breeding in Cats of other colours. 



In addition to the three principal mutations, 

 black, red, and white, other colours may be seen in
