    Yes!!!!

    There is a risk if a kitten's blood group is different to mum's blood group.

    Ab mum to b stud will have kittens that are either Ab or b. The b kittens will be at risk from fading kitten syndrome if they suckle from mum for the first two days.

    Best way to think about it is that AA queens can go to any stud. bb queens can only go to bb studs. Ab queens can only go to AA studs.

    Some people take the risk and then hand feed kittens for the first day or two as it is the colostrum that has the antibodies that attack the blood cells. Others think that b kittens to an A mum are okay or at virtually no risk but they are at a risk.

    There are 3 blood groups but 4 possible combinations when it comes to mating decisions for breeds affected by blood groups. There are:

    • AB
    • AA
    • Ab
    • bb

    AB is a blood group on its own & not a whole lot is know about this group when it comes to matings as it is uncommon.

    AA is a "pure" A group and bb is a "pure" B group whilst "Ab" is an A group carrying the b group - confusing because written down it looks like AB.

    ANY MATING that has a risk of kittens being of a different blood group to mum is potentially lethal.

    Please refer to this guidance:

    Dr. Addie - Feline Blood Groups

    Mum Ab should be mated to an AA only
    Mum AA can be mated to any
    Mum bb should be mated to bb only

    There are a few breeds. Birmans, BSH, Rexes and others that I am probably not aware of.

    well this particular breeder had 4 kittens and 1 died so im betting that thats the reason it died.I dont think its a risk worth taking. She obviously does:(

    Makes sense as that will be where Birmans got it.

    It's possible. Usually kittens affected by kitten fading syndrome, 'at best' lose part of their tail and 'at worst' die in the first few days.

    Some breeders are set in their ways, sadly.... Why bother testing their blood groups if they are going to ignore the risks? :rolleyes::

    B type blood groups. Most breeds have A type only.

    ah i see what you mean and yeah what is the point in testing if she is going to ignore the risks.Even talked to a 3rd breeder why told me she doesnt bother to blood group test her cats she said 'there are more important things to worry about' i cant believe it myself.

    I've been studying this in more detail since last year's litter and here is the situation:

    Group A has a dominant inheritance over Group B.

    Group B cats have very effective antibodies against the red corpuscles of Group A, so when a B queen is mated to an A stud, the litter will be group A - they will be born healthy but when they take and ingest the first milk (colostrum) and therefore the antibodies of their mother, this will destroy their red corpuscles, which leads to death.

    Group B males can be bred to Group A and B females, without exception.

    Group A males can only be mated to Group A females.

    Group B females can only be mated to Group B males.

    Group A females can be mated, without exception to Group A and B males.

    The problem happens when Group B queen is mated to a Group A stud, you don't want Group A kittens to be born to a Group B mother!

    My girls are Group Ab and i am using both A and B studs without issues. :)

    I completely disagree, Alison. There is a risk for B group kittens to a A group mum.

    Dr. Addie - Feline Blood Groups

    I think a lot of breeders are chancing Ab to B group studs. Kittens should not have a different blood group to mum.

    I haven't heard of anyone losing any kittens after this mating, have you?

    I know of several breeders who abide by the rules i posted above and have never had problems.

    There is always going to be variations of rules but i stand by what i've said.

    As outlined in the above [and extensive] article on the topic of blood groups in cat breeding - the more a A type dam has B type kittens the more the antibodies build up....

    Hell of a risk to play anyway - we're talking about lives if not abnormalities of kittens.
