Sapphire Cornish Rex Variant with her red kitten.
Sapphire's sire is a Lilac
Colourpoint British Shorthair. Outcrossing: At Myskanco Cornish Rex, we believe in using Cornish Rex
variants to expand our Cornish
Rex gene pool.
I am really pleased with the results of
this outcross mating, between Mutadarra and Rhapsodyinblue.
Uno is a Blue Tortie,
and now a Champion. She has also won 2 GCC,
and 2 RGCC at GCCF shows. At present
(June 2009), Uno, is
on maternity leave, rearing 3 Cornish Rex. She is a very doting mum, very loving
and protective towards her kittens.

Explanation on Cornish Rex outcrossing:
In the UK, to expand the small Cornish Rex gene pool, we are allowed to
outcross, to a number of other breeds (GCCF rules).
2006 has been a successful year for our Cornish Rex outcross programme.
2 of our queens have successfully delivered Cornish Rex and Cornish Rex
variants kittens, therefore expanding our gene pool still further with Russian Blue, British
Shorthair and Oriental genes. These 2 litters are a continuation of our outcross programme, and more plans are afoot.
The
year 2008 will bring in more outcross genes, but that is another story!!
The Approved list of breeds, include the Abysinnian,
Asian Shorthair, British Shorthair, Burmese, Oriental Shorthair, Russian Blue
and the Siamese.
For my outcrosses, I have used Oriental Shorthair,
British Shorthair and Russian Blue outcrosses.
Cornish Rex and Devon Rex genes are not compatible, and any mating between the two, is
highly undesirable. Kittens of any such mating,
will be registered on the Reference Register, and not considered to be Variants. They cannot
be
used in either a Cornish or Devon breeding programme. When undertaking an outcross, it is best
to know, the blood group of both cats.
In cats, there are 3 blood groups, A, B, and AB. Blood group A is dominant to blood
group Ab and B,
and Ab is recessive to blood group A, but dominant to B. Blood group A (dominant)
produces no
antibodies, or very weak ones, to blood group B. Blood group AB cats produce
no antibodies,
against either of the other blood groups. Blood group B produces powerful antibodies
to blood group A,
and these anti-A antibodies can cause serious problems.
Burmese, Orientals, Russian Blues, Siamese are exclusively type 'A', and approximately
60% of
British Shorthair are group 'B'. Fortunately, the kittens are only at risk, from the effects of the maternal antibodies,
for about their first 16-24 hours of life. Then the kittens gut lining becomes impermeable,
and the maternal antibodies are unable to pass across it, into their blood stream, and cause
damage. It is then safe for blood group A kittens, to be returned to feed from their blood
group
'B' mum.
Recent research suggests that the critical period, for keeping kittens, from their mum
may be
as little as 16 hours. To be on the safe side, it is advisable to keep them away 24 hours.
