===Feline neonatal isoerythrolysis===

Although feline neonatal isoerythrolysis (FNA) is rare, the mortality associated with it is high. Cats have three main blood types, type A, type B and type AB. Cats with type A red blood cell antigens have weak anti-B antibodies, and cats with type B red blood cell antigens have strong anti-A antibodies. FNI develops when type B blood mothers mate with type A tomcats. FNI affects the type A (and rarely the type AB) kitten born from a type B mother following ingestion of maternal colostrum containint anti-A antibodies.  

Although feline neonatal isoerythrolysis (FNA) is rare, the mortality associated with it is high. Cats have three main blood types, type A, type B and type AB. Worldwide, the most common blood type in cats is type A.

 

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. FNI affects the type A (and rarely the type AB) kitten born from a type B mother following ingestion of maternal colostrum containing anti-A antibodies.
