===Feline neonatal isoerythrolysis===

Cats have three main blood types, type A, type B and type AB. Worldwide, the most common blood type in cats is type A and type A is dominant over type B. Queens with type B blood have high levels of naturally occurring alloantibodies to type A blood. FNI develops when type B blood mothers mate with type A tomcats producing kittens with type A/B blood. The newborn kittens ingest maternal colostrum containing anti-A antibodies leading to the clinical signs of feline neonatal isoerythrolysis (FNI).
