Snowshoe Cat

The
Snowshoe Cat is a deliberate hybridization of
the Siamese and
the American Bicolor cats. The breed began in 1960 in Philadelphia,
USA. This was an era
when a number of new breeds were being created or discovered.
This is a rare breed.

After the creation of the breed, its
development included breeding Snowshoe to Snowshoe.
On the basis of good breeding (including being well socialized), the American Shorthair
is a gentle, amiable and very agreeable cat. They look like cats used
to look.
Likewise for the Traditional "old-fashioned" Siamese. The Siamese
cat's character is slightly different from the American Shorthair but
all the same she has a well rounded character suitable for human
companionship; albeit demanding and talkative at times.
It is no surprise, therefore, that the Snowshoe Cat
also has all the
qualities required of a fine all round domestic cat namely, friendly,
calm, talkative, accepting of other pets, companionable,
the intelligence of Siamese and amiability of the
American Shorthair and enjoying being indoors.

The same well balanced normality of this cat extends to her body
conformation. She is medium sized, muscular and athletic. She has some
of the solid build of the American Shorthair but is not cobby like the
Persian. She has short hair.
She would probably be a 400 meters runner if she were a human
athlete.
Coat
The fascinating aspect of the Snowshoe Cat and the cat's outstanding
feature must be the coat pattern. After all, this cat is named after
her coat
pattern. I therefore go into some detail about the
coat color and pattern despite the fact that it means discussing cat
genetics, a very complex subject that is still being researched. Indeed
at 2005 in an article entitled "White spotting
|

in the domestic cat (Felis catus) maps near KIT on feline chromosome
B1" by M. P. Cooper, N. Fretwell, S. J. Bailey and L. A.
Lyons,
it was stated that "the gene(s) responsible for white spotting in the
domestic cat have not yet been identified". I deal primarily with the
Bicolor Snowshoe (the photographs illustrate the Bicolor). There are
mitted and pointed coats as well (see below).
White Spotting Gene
As I understand it the white
spotting gene causes the bicolor pattern through its
interaction with a recessive allele (see below) of the agouti gene.
Its action is modified by (a) modifier genes and (b) whether it is
present in heterozygous form (2 copies of the gene) or homozygous form
(one copy present). The white spotting gene is semi-dominant with
variable expression (is this because it is modified?). Remember genes
come in pairs and one of the pairs is called an allele.
This gene is imported into the Snowshoe cat by the Bicolor American
Shorthair. The white spotting gene interacts with the Siamese
gene
and overlays on top of the pointing pushing out the dark pointing
caused by the Siamese gene to produce the white markings on the face,
limbs and front of the cat.
Apparently, some researchers have hypothesized that there are various
types of white spotting gene and one of these is the direct cause of
the "mittens" (snowshoes) on this cat.
Himalayan Gene
The Siamese
gene is
called the Himalayan gene. The gene is recessive to the full color gene
meaning both allele (2 copies) of the gene need to be in place for the
Siamese color to be present.
Interestingly the gene is also heat
sensitive. It is this particular characteristic which explains the
"pointing" or dark extremities. The extremities of an animal are
obviously cooler than the center. Under warmer conditions the gene
produces a lighter color (the Siamese body color) and under cooler
conditions the gene produces a darker color.
This explains why the Siamese cat is darker during the winter
months
(particularly is she goes out a lot) and pure
cream or white without points at birth (at
the moment of birth the kitten will be at internal body temperature).

The same applies to the Snowshoe cat. At birth they are white and they
develop their markings over the first 3 weeks.
Another interesting point is that Siamese cats get darker with
age and it has been reported
that the white areas caused by the spotting gene
may increase with the cat's age. Is the spotting gene heat sensitive
too?
This would imply that the white markings of the Snowshoe Cat might
expand
slightly with the age of the cat and that there is greater contrast
with age.
Breeding
Through selective breeding Snowshoe
Cat breeders
are, it
seems, able to control to a degree how the white spotting gene will
work. This is important as the preferred show patter is the inverted
"V" on the face as illustrated in the pictures at the top of this
page. This is a symmetrical pattern co-ordinating well with the Siamese
points and the geometry of the face.
Although, please note that the TICA breed standard does not give more points
if the pattern is symmetrical.
The white spotting gene is possibly (some conflicting information here)
associated with deafness, blue eyes and odd eye color if it has
affected the area of the ears and eyes. Note: the Messybeast
author Sarah Hartwell states that this is not the case. Deafness is
associated with the white gene (a different gene), however.
A Mitted Snowshoe
has white on the paws, chest, back legs and chin only. The Pointed Snowshoe Cat
has pointing like a Siamese and no white patches.
The Snowshoe Cat has full TICA registration (can be shown at
competition)
but is not
registered by the CFA. The top UK registry, GCCF, has preliminarily
recognized this cat.

As usual I select breeders from Internet wesbsites only. The
status of the website in terms of Google
PageRank and Alexa traffic rank is indicative of the effort invested in
it and therefore the cattery. The content of the site will also tell
people a bit about the philosophy of the breeder. I try and select individual cattery websites (as
opposed to directory listings) listed in the first three pages of a
Google search and add my comments.
Karib's
Kats
Located Long Island NY, USA. Has an Alexa traffic rank of 9m (low) but
at least ranked and a Google PageRank. Guess it has been around for a
while -
at least 10 years or more. Very small website.
This is the only
Snowshoe
breeder's website listed in the first three pages of Google indicative
of the rarity of this cat (note: there are directories,
however).
Snow
Angels Snowshoe Cats
Not sure where they are located as it's not clear from the website.
They have a PageRank and 6m Alexa traffic rank. Not in first 3 pages of
search. This is the only cattery for this breed listed by TICA on their
website.
Some UK breeders
None of these sites are listed in first 3 Google search pages.
Snowshoe
Cats UK (link)
Listed
in a directory. Nice looking site; no traffic rank and a low PageRank.
Based in Plymouth, Devon (SW England)
Glittakitz
Hobby cat breeder located off junction 29 of the M1 near Holmewood (nr.
Chesterfield). TICA and GCCF registered.
Snowshoe
Cat Society (link)
Not a breeder but lists the above two breeders and more.
