We've got two white kitties with blue eyes and
seal point markings. If they mate, and please let
us know and I know you will, if it's okay for
brother and sister to mate, will the offspring be
white with blue eyes, similar to the parents?

I would assume that blue eyes and white color
are recessive traits, but I'm not sure at all, so
I'm asking you guys. Thanks. : -)

No, it's not ok to let brother and sister mate.
Your odds of having kittens with a multitude
of health problems is pretty high.

Secondly..there is no way to accurately predict
the color or markings of the offspring.  If you
breed purebred cats and know the lineage you
can make a really good guess...but even then
you get the occasional surprise.   My foster
cat was a grey striped tabby.  She had 4 kittens,
one with seal point markings, one white with
blue eyes, one calico and one all black...go figure.

More importantly...hundreds of cats are killed
every day because their aren't homes for them.
Non pure bred cats...even ones that look like
seal points....are pretty common in shelters all
over the place.  It will costs you more to breed
them then you will ever get out of it financially
and if you or someone you know wants a cat
with those particular markings the most expedient
(and best) way to get one is to go to the shelters and
save a life.  Spay and neuter your kitties now.

We never, never thought of making money from
this. My wife found homes for 16 kittens one weekend
last month, and felt that the people were good and
she screened them. These cats are so special its
hard to describe. It's really about temperament and their
attachment to us. It would be nice if their offspring
looks like them but that's not that important, especially
after the kittens arrive, but if what you say is true and
I think it probably is, then we won't be doing this because
of the gene thing. Thanks : -)

I understand having an animal so special to you that you
want to breed it...really.  My pedigree golden retriever
had the best temperment of any dog I had ever come
across ...even for a golden.  I just knew her puppies
would be ultra special and I would easily fnd great
homes for them.  Here's the thing.  There are a lot of
ultra special dogs in the pound with a death sentence
because there just aren't enough homes.  I would do better,
(as would your wife) to find homes for those dogs than to
breed even more.  Seriously...take a trip to your local
animal shelter and meet some of those animals.  If your
goal is to give great animals homes than you will find
an unending source for those animals in cages at your
local shelter.

We've decided to not do this. As far as getting animals
from the pound though, we haven't had much luck. This
with cats. We have had very good luck with feral cats,
ie kittens. We've done a few TNR, but the way the local
shelter butchers their ears is hard to take. I know I'm a
wussy, but it just bothers me.

The cats I've loved the most are the two that had kittens
in our home. We found homes for all of the kittens. The
mothers both seemed to appreciate so much the attention
that I paid to her and the kittens. It might be the most intense
bonding I've ever had with an animal. They both raised
their kittens under out bed and I could reach under the
headboard and position the babies on the mother's nipple.
They both were like so grateful. And they seemed to trust
me to take care of the babies when they went out
for a break.

But like I said, we've decided not to mate them. I posted
to another group and got a detailed answer from a vet who
even more strongly stated the negatives.

    Yeesh.  No, it's not okay for a brother-sister mating.  If you
knew their pedigrees inside and out, including all health details
going back 10 gens or so, it *might* be okay to do a linebreeding this
close, but only if there was some incredible recessive feature that
needed to be locked in.

>I would assume that blue eyes and white color

    Yes the traits are recessive, but it's still not a good idea
to mate these cats.  Honestly, before you get into breeding at all,
you need to learn a lot more about genetics and your chosen breed, as
well as knowing more about exhibiting and the necessary genetic health
testing that needs to be done before breeding cats.

Please, don't mate brother and sister!  I had a cat that came from siblings
(I didn't know until recently), and she just died at the age of 9 from
congenital kidney problems.

This is a terrible idea!  (and to be honest, a little gross!)

It's not gross to me, but it is seriously sounding like a bad
genetically. We aren't thinking about breeding though, just
one litter because my wife wants them to experience, well
the female, motherhood, and it would just be so cool to see
how they get along as parents, they sleep with each other
almost all of the time and are very affectionate. They were
feral and after being separated from their mother had only
each other.

Since white cats with blue eyes have a very high incidence of deafness, it's
not a great idea to breed even non family members.  It's the worst possible
idea to breed two white kitties with blue eyes that are brother and sister!
THE WORST!  Not only will the deafness issue be reinforced, unless you know
the pedigree of  your cats several generations back, there are probably
other health issues that would receive a double whammy on the genetic front.
Things like heart disease, cancer, and severe allergies that can affect them
as young adults.  Not to mention outright deformities that either kill the
kittens in utero or while they are still kittens.

Do you know how many animals are put to death in shelters every year?  We're
a very small shelter serving a small community, and we put to death over 75
animals each year.  The larger metropolitan shelter in the city just north
of us puts that many cats to death every day.  Every day.  Most of these
cats are from people who either have "oops" litters because they didn't spay
and neuter their cats soon enough, or because they were pet owner who bred
their animals deliberately for the worst possible reasons.  The worst
possible reasons include trying to create more cats like the parents,
especially when neither are registered.  Every single kitten produced by
back yard breeders means that a kitten in a shelter somewhere dies because
those kittens find homes and the shelter kittens don't.  And, unless you
know a whole lot about how to screen potential adoptors, your kittens might
be ones that end up in a shelter and dead as well.

You like white cats with blue eyes?  I see them every day.  Mostly they're
siamese mix somewhere along the way, and our itty bitty shelter has two
right now.  It's not unusual or special, except to the owners.  And, like I
said, a lot of health problems go along with them.  I know that personally.
I have a siamese mix white kitty with blue eyes and he's deaf in one ear.

Get your animals fixed, and do it now.  Cats can get pregnant as early as 5
months, so time is critical.  Do it before sexual maturity, because all
those hormones increase the chances of cancer and you certainly don't need
do that, as that's also higher in white cats with blue eyes.  If you need
financial assistance to have this done, then look at www.spay.usa.org/ for
direction to a low cost vet in your area.

>Since white cats with blue eyes have a very high incidence of deafness,  

Sometimes, it is possible if these cats are pointed that they are
carrying the gene for Siamese Blue Eyes and will not be deaf. That
doesn't mean I think that breeding them is a good idea. :)

http://www.messybeast.com/whitecat.htm

There is an established link between the white coat color, blue eyes
and deafness. The deafness is linked to the gene for blue-eye(s)   Not
all blue-eyed whites will be deaf since there are several
different genes causing the same physical attributes (whiteness,
blue-eyedness) so it all depends on the cat's genotype (its genetic
make-up) not its phenotype (its physical appearance).

If the cat is a Foreign/Oriental White, it carries the gene for
'Siamese Blue Eyes' which is not linked to deafness
(the gene for Siamese Blue Eyes is linked to cross-eyes instead).
Siamese blue eyes lack a reflective tapetum and
give red-eye with flash cameras. Random matings can mean that this
gene sometimes appears in non Oriental-looking cats which have
colorpoint cats in their ancestry.

Geez, that is one of the most informative posts I've ever gotten.
The color really wasn't important though, just that they are so
sweet and both used to be feral kitties that it would be nice to
have a little family that looked like each other. We have decided
not to do this though, honest.

If the white cats, Killer and Snobol, have red eye then they are
probably Siamese white, interesting. We call them K & S because
one of them bit me really hard and almost broke my knuckle
while they were becoming non-feral. I didn't know which one
it was so we named one Killer, but we don't know which one it
is. So when we talk about them it's either Snobol with the crooked
tail or Snobol with the straight tale, or Killer with the crooked tail...
: -) It's kind of hard for me to believe how sweet and unafraid they
have become. They are now the nicest cats we have, and we
have a bunch. They both sit on top of one of the arms of a couch
and wait for people to walk by and pet them. They aren't even
afraid of people's feet and they both come when we call, especially
if we make a little distressed kitty noise that they used to make to
each other when they were younger and only trusted each other.

For people who think cats aren't individuals and don't have
personalities... you wouldn't think so after 3 minutes at our
house.

Good god.  Do you think it would be ok to mate with your sibling?

Get your cats neutered, pronto.
