GeneticBlood groups of cats and the “ Fading Kitten Syndrome “
Also like humans, cats can have different bloodgroups. Most cats have the bloodgroup A. However, it also happens the bloodgroup B or A/B. One supposes that approx. 10 – 20 % of the Birman cats have the bloodgroup B and low interest in Birmans have the bloodgroup A/B.
The vet can test the bloodgroup of the cat. However, these tests are not always unambiguous. So the test can prove a cat with bloodgroup A, but this can state nothing wheter the cat also carries genetic arrangements for the bloodgroup B. The assesement to the bloodgroup B can transmitted namely covered. Therefore it can happen, that with a mating of two bloodgrouped A cats, although kittens appear which have the bloodgroup B.
The reason why there can maybe appear some problems , when you breed without knowing the bloodgroups of your cats is the so- called “Fading Kitten Syndrom”. Matings between bloodtyped B female cats to typed A tomcats, can call forth the “ Fading Kitten Syndrom”. That means the typed B cat can form antibodys against bloodgroup A. If a kitten with bloodgroup A drinks the milk of the typed B mothercat, the kitten can react with incompatibilitys against the mothers milk. This incompatibilitys can lead to the death of the kitten. But it`s no problem to breed with bloodtyped B female cats, if you follow some rules. For example you can exclude the Fading Kitten Syndrom, if you avoid to mate Typ B female cats with typ A tomcats. A non-problematically mating is between a typ B female cat with a typ B tomcat. So with knowing the bloodgroups of the cats, it`s easy to exclude the explained problems.
Breeding with a bloodtyped B tomcat is no problem at all, because only the female typed B cats can build antibodys. A bloodtyped B tomcat can be mated without problems with typed A and typed B female cats.
αυτο δεν ισχυει (τουλαχιστον με τις πηγες που ειχα διαβασει εγω)...το ειχε βάλει και η Δαναη αυτο....καλυτερα καντε τις εξετασεις και τα βλεπουμε μετα ολα
