Thank-you for responding to my question about inbreeding. I did try looking on line for genetic information, but was unsuccessful. I feel since I have been researching about FIP, I have found so many factors that affected the development on FIP for my sweet kittens. They were inbred, they were exposed to a carona virus in the cattery they were born, they were given expired vaccinations by the breeder, and the more I research, the more I find out. It's sad to think that a breeder could do this and deny it all and retire the parents and brother of my kitttens, and purchase a new male, and continue to breed and sell kittens without any reguard to what has happened to my kittens, or have any compassion for the grief myself and my family are experiencing. There are so many breeders out there, that I am learning are compassionate, and truely love their cats and kittens, but I happended to pick a lemon of a breeder.
Unfortunately there are those out there that just want to make a quick buck. Since you were unable to find out about genetics let me explain it this way. All cats have 2 genes for each trait, one from mother and one from father. So let's say the the sire has some sort of deformity but because he has one good gene from one of his parents and one bad gene from the other he carries for the defect but he dosent show it because the good gene compensates for the bad one. Lets pretend his genes look like this: N for normal and d for defect so his set would be Nd
. Ok so now you have a queen that has no defect and her genes look like this NN
because she does not have the defect. Now each parent passes one gene onto thier offspring. So in a litter of 4 kittens the kittens genes will look like this: 2 with NN and two with Nd (so two that are normal and two who carry
for the defect but appear normal)(or NN,NN,Nd,Nd
Now here's where the inbreeding comes in- say you take one of those kittens whom carries for the defect (Nd)
but you don't know they carry and breed it back to the father who carries (Nd)
the defect. Now you remember that each trait contains two genes, one from the mother and one from the father. So now out of four kittens you get this:1 normal, 2 that carries but are normal,and one with the actual defect (or NN,Nd,Nd,dd
). See how inbreeding can bring out defects in cats?
If you were to then even go further and take the one with the defect (maybe you don't know the cat has a defect because it shows itself later on) and breed it again back to the father or one of the sisters/brothers who carry the defect you would get this:1 carrying but normal,and three that have
the defect or (Nd,dd,dd,dd
So is it worth it to inbreed? To me NO
unless the breed is being established and there's no other way to bring out the traits that make a breed what it is. It is good to outcross with new blood every so often and then breed back the desired traits eventually.
Unfortunately many breeders inbreed too closely because they don't want to spend money on buying and maintaining another cat with different bloodlines, these kind of breeders do not know what thier cats carry and are doing it for the wrong reasons.
Other breeders do it to bring out a trait that is really desirable to the breed but if doing it for that reason (which is a legitimate reason) they need to be very careful that none of the cats used carry a genetic deformity. If any of them are found to carry a deformity they should not be bred AT ALL!
Cats that are inbred can have all kinds of immune system problems and therefore can surccomb to diseases that other cats may not catch.
If you ever buy another purebred ask to look at the cats pedigree to see if there is too many closely related cats on the pedigree. A breeder should not have a problem with showing you that info.
Just a note on the FIP situation-any cat with the corona virus will test positive with that virus and any cat that was vaccinated against FIP will test positive as well but only a small percentage with that virus actually get FIP. The breeder may not have known the cat had FIP or the virus could have mutated later after the cat left the breeders. So in that regard the breeder can't really be blamed. However
, if she has a bunch of sick cats because of too much inbreeding, that would be her fault.
