- Whited Expression
- The results of other breeders who have worked with the ALC whited factor
have shown that often the underbody colour will or can indeed be lightened
by the presence of these genes in the genotype of the cat, i.e. when mating
a true whited hot sorrel, for example, with a "light tummied"
SBT, often the results were an even lighter underbody. The true ALC white
is, however, a clean "T-shirt" white and not to be confused with
light cream, beige, light tan, etc. Cats showing whited expressions have
been very important in the extension of the breeding basis for the true
whited underbody pattern.
-
- Groundcolour influence
- With the lack of genetic research and authoritative opinions on this
aspect, I am writing my assumptions based on the breeding results of numerous
others. Here I have Carol Effinger
(Sutera Bengals), Lisay Arvay (Rosetta Bengals), Jean Mill , Annette
Trolle (Trollspotting Bengals) and others to thank for many patient
hours of question/answers.
-
- The groundcolours of our Bengals seem to have a distinct and pronounced
influence on the visual clarity and extent of the whited factor. The highly
glittered, red mahogany-brown to browned-orange (more richly-pigmented
rufous spectrum) colours seem to possess higher concentrations of modifiers
that darken or reduce the whited expression and, so far, the non-glittered
wheaten, light gold, yellow-bronze groundcolours seem to have a more confined,
stable pattern when in combination with the whited pattern, i.e. not migrating
as far into the underbody pattern. This is not always the case, of course;
the Phantom F2 and 3's mentioned earlier are a richly browned rufous with
black pattern. There are, however, glittered beige, tan and lighter, cooler
colours which have had true whited ALC underbody patterns. Glitter was
inherited independently of colour; clean and pure white seemingly were
not. Not at this stage.

- Most of the numerous richly-rufoused (mahogany red to ruddy Abyssinian)
colours, whited-looking kittens purchased, viewed and/or researched for
this article lost their whited underbody pattern by full sexual maturity.
Some of these kittens kept the much lighter chin and spectacles like in
the red Abyssinian ruddy colour pattern, giving the impression of the whited
expression in the face only. The colour descriptor "rufous" is
also difficult to nail down, but a simple explanation told to me sums it
up well: rufous is like iodine - the thinner the application, the more
yellow-bronze the colour, the thicker the application, the more mahogany
red the colour becomes. It seems that the higher the concentration of red,
the higher the concentration of underbody colour modifiers.
-
- The best whited examples to date had the ground colours: wheaten, light
brown, golden, bronze, sorrel, beige, tan, etc. - in other words, the lighter
and "cooler" colours. It also seems, visually speaking, that
the richly rufoused, "ruddy" Abyssinian colour, complete with
its lighter to near-white chin, spectacles and evenly-reddish underbody,
is the same genetic red as in many of our red-rufous Bengals. We know that
the foundational Millwood Dehli was a richly rufoused, which contributed
to both glitter and red in the breed today, but also that Abyssinians were
employed in the first filial foundations. We do not know, however, what
the genetic makeup for Dehli's red pigmentation was.
-
- Snows
- Some snows seem to be whited due to their temperature-sensitive expression
of the colour point genetics, the warmer areas lightening, the cooler areas
darkening, with their underbodies being sometimes many degrees lighter
than their overall body colour. This should not be confused, however, with
the ALC whited underbody pattern described here. Many breeders told me
in my search for whited cats or parents of kittens, that their snows were
their only whiteds, so this aspect may be easily confused with the true
whited ALC underbody pattern. I have found, interestingly enough, a concentration
of whited expression patterns in BSTs in certain lines in a few American
and European pedigrees (in particularly in the UK, Denmark and Holland)
with Lynx, Mink and Sepia snows in their genotype.
 An excellent
example of this is the breeding programme of Annette Trolle of Trollspotting
in Denmark.

- Selecting for the Whited Underbody Pattern
- In breeding and selecting for ALC whited patterns, the true test is
to wait out full maturity of the cat that showed the right phenotype as
a kitten, perhaps 1.5 - 2 years, before considering it " ALC whited".
Then, one would breed only with such cats, but... due to the rapid pace
at which many catteries change out breeding animals, perhaps this aspect
will be one of the slowest to be developed in the Bengals of tomorrow.
Most people don't want to tend to a cat for such a period of time before
deciding its final place. As a plant breeder, I often wait out 4 - 6 years
of evaluation before judging the results and deciding what to employ further
in breeding.
-
- Selecting kittens
- Many Bengal kittens seem to have whited underbodies because they are
usually very light to white underneath, but this often changes rapidly
at sexual maturity to the groundcolour of the upper body. It seems obvious
that the modifiers "kick in" at certain stages of development,
as is with the coat colours of Bengals, and what looks like ALC whited
underbody pattern creams out or darkens. It has been a very frustrating
experience in the search for the true whited expression to be proposed
or even sold kittens as "true whited" when they were simply in
the kitten coat with lighter underbody. The true test, as mentioned, is
to wait out full maturity of the cat, at least 1.5 years (better 2 full
years), to even describe it as "true whited". It would be more
honest to describe the others as just "lighter" in the underbody
pattern. Choosing a kitten from two, fully-mature whited parents is one's
best bet.
-
- As previously mentioned, white x white breedings are already slowly
becoming a possibility, but not a 100% probability of true whited offspring.
According to 2 experienced breeders, a few factors to look for when suspecting
the presence of a true whited kitten is a bright pink, practically naked
underbody at birth with black to dark spots. ( pictured
at left: Casarocca Cadenza Inglese at 2 weeks, completely naked; below,
Casarocca Tempesta Notturna at 8 weeks) An important rule of
thumb is that the longer the kitten displays the near
 nakedness with
brilliantly white "fuzz" slowly giving way to pure white fur,
the better the chances are that the ALC whited factor is present! However,
in one repeated mating I know of in which two true ALC whited parents were
used, the kittens were born with dense, brilliantly-white fur on their
underbodies.
-
- Another breeder has had the experience that their true whited SBTs
were all born with pink pawpads (darkening very shortly thereafter) and
faces. Another interesting aspect of the ALC whited genotype being present
in our SBT Bengals was described to me as the fact that the brilliant white
fur, once wet, had an odd cool greyish (not brown or cream) tinge to it,
i.e. the undercoat had an almost dull blue hue to it that became visible
when wet. Once dry again, the white colour was the only hue visually perceivable.
Of the cats that we own with the actual, true ALC whited underbodies, the
white is brilliant, clean and just below the white there is this cool grey
undercoat.
-
- Here, on the left, is a picture of our CASAROCCA LOREN QUEST at 10
months and still extensively whited. I feel that she will hourglass somewhat
on the tummy, but should keep a large portion of her large ALC underbody
pattern. To the left of LOREN QUEST is our SUTERA TATIANA girl, FOREVER
YOURS. FOREVER YOURS, aka Luthien, remained completely naked underneath
until 16 weeks!
-
- VERY IMPORTANT - no SBT programme can claim to produce 100% ALC whited
cats, so a kitten, even though brilliantly whited, may not develope the
phenotype of its parents. The best thing to look for is:
- 1) the lack of background pigment around the head, t
- 2) he presence of black or dark brown in the pattern and
- 3) a completely white to nearly-naked underbody pattern. The kittens
should still have this kind of phenotype at "selling age" of
10 - 14 weeks. If there is cream or brown in the whited area at this age,
the cat will not become and Adult Whited.

- Wish us luck - more than luck!
- My personal feeling is that the brilliant ALC whited underbody will
be one of the additions to the Bengal of the future and it is exciting
to have such a project to work on. Wish me luck! : ) I would also like
to express my gratitude to Carol Effinger, Lisa Avray, Jean Mill and others
for their assistance and patience.
