Not especially. (I guess it depends on what you consider "rare"; one source I found indicated that about one out of 20 cats was white.)
There are three ways a cat can turn out white:
It can have the gene for white coat color (self white... what you probably mean by "pure white").
It can have the gene for white spotting, and be "spotted" so extensively that it appears to be self white with maybe a few colored hairs in some inconspicuous place.
It can be an albino, meaning there's a genetic defect such that it doesn't produce the normal color pigments despite having the genes for them. (There are several different reasons this can happen.)
There tend to be less white cats than other colors, but I wouldn't say they are rare.
I have a pure white cat and it likes humans.
when they are bor they are pure white
The rare white tiger is the same size as a normal tiger.
a pure breed Siamese is pretty rare to find and they die pretty fast.
yes that would be pure MDMA its rare
A pure white hamster isn't very easy to find, especially in pet stores. If you have a hamster breeder, it will be easier. If you want a white hamster, you should get a Winter White dwarf hamster. They turn pure white in the winter and are adorable. Occasional spots of white on a hamster isn't rare at all, though. It's very normal.
The Russian cat is often considered quite rare. White cats are more difficult to find and most people have luck with going through a breeder.
My answer to this question is yes. These animals are very rare and are almost COMPLETELY endangered.
blue eyed cats with pure white long hair(and sometimes short hair) are more likely to become or be deaf
Yes. Male tortishell cats are rare
Black, brown (chocolate), white, blue (smoky or dark grey), red (orange), white and cream. There are many variations of these basic colours and many different patterns.
White tigers are merely a rare color morph of the Bengal. They are large, powerful cats that love water, and are an endangered species.
