Answer: C - The cause of neonatal isoerythrolysis, or "fading kitten syndrome", is a blood type B mother cat's incompatibility with the kitten's blood type. When the kitten nurses the colostrum, incompatible maternal antibodies can attack the blood cells of the kitten and cause severe hemolytic anemia. These kittens appear healthy initially, then suddenly fail to thrive and eventually die.
