Breastfeeding is a crucial step for the health and development of kittens. However, there can be complications if the cat mother and kittens have incompatible blood types. Here is a detailed article on this subject :
Blood groups in cats
Cats have three main blood groups: A, B and AB.
Group A :
This is the most common blood type in cats. The majority of domestic cats have this blood type.
Group B :
This group is less common and is primarily found in certain cat breeds, such as British Shorthairs, Devon Rexes, and Cornish Rexes.
Group AB :
It is the rarest blood type in cats. Cats with this blood type can receive blood from groups A and B.
Importance of blood groups :
Knowing your cat’s blood type is essential in the event of a blood transfusion and in the context of reproduction. Ask your veterinarian for advice if in doubt.
Breastfeeding and Blood Group Incompatibility in Cats
Breastfeeding is essential for newborn kittens because it provides them with necessary nutrients and antibodies to strengthen their immune systems. However, a blood type incompatibility between mother and kittens can lead to serious problems, including a condition called neonatal isoerythrolysis.
What is Neonatal Isoerythrolysis ?
Neonatal isoerythrolysis is a hemolytic disease that occurs when antibodies in breast milk attack kittens’ red blood cells. This usually occurs when the mother has blood type B and the kittens have blood type A. Anti-A antibodies in the mother’s colostrum can destroy the kittens’ red blood cells, leading to severe and potentially fatal anemia.
In summary :
A female cat with blood group A can mate with all males because she can nurse all kittens regardless of their blood group, her colostrum contains very little anti-B antibodies, however, you must remain vigilant if the kittens are growing poorly or if they show signs of anemia or lethargy.
A female cat with blood group B can only mate with a male with group B, otherwise the kittens are poisoned by colostrum because it is composed of anti-A antibodies.
A female cat with blood type AB can mate with all male cats regardless of their blood types and breastfeed the kittens without problems.
Precautions to Take
1. Blood Group Test : Before breeding or before mating, it is recommended to test the blood groups of the female cat and male cat. This makes it possible to predict the risks of incompatibility and to take preventive measures.
2. Monitoring Kittens : After birth, monitor kittens carefully for signs of anemia, such as lethargy, pale gums, and poor weight gain.
3. Temporary Separation : If an incompatibility is suspected, it may be necessary to separate the kittens from their mother for the first 24 to 48 hours, or prevent the kittens from suckling the mother by using a special bodysuit (be sure to choose the right size), during which time they receive colostrum. During this time, kittens can be fed colostrum replacement.
4. Veterinarian Consultation : Consult a veterinarian for specific advice and additional tests. The veterinarian may recommend blood transfusions or other treatments for affected kittens.
5. Regular Monitoring : Make sure to regularly monitor the health of the kittens and the mother. Frequent veterinary visits can help detect and treat any complications quickly.
By taking these precautions, you can minimize the risks associated with blood type incompatibility and ensure healthy, happy growth for your kittens.
