Bleeding disorders are diseases in which the blood does not clot normally, causing a tendency to bleed abnormally or excessively after minor bumps or cuts. The effects on your pet are related to how much blood is lost and where the bleeding occurs. 

Hemolytic Anemia in Cats

Hemolytic anemia is a disease process in which the red blood cells, the cells that carry oxygen and impart a red color to blood, are destroyed, resulting in a decreased number in the bloodstream. This is often a rapidly life-threatening condition. 

Immune Mediated Hemolytic Anemia in Cats (IMHA), Autoimmune Hemolytic Anemia

IMHA is a disease in which the body’s immune system, which is designed to attack and kill germs, attacks and kills the body’s own red blood cells; it occurs more often in dogs than in cats and in middle aged females 3 to 8 years old. 

Neonatal Isoerythrolysis

Neonatal isoerythrolysis refers to the destruction of the red blood cells (erythrocytes) within the kitten's body system by the action of maternal antibodies, which gain access to the neonatal circulation through the colostrum. 

Thrombocytopenia in Cats

Thrombocytopenia refers to an abnormally low blood-concentration of platelets, which are blood cells that promote blood clotting after injury to the lining of the blood vessels. When the concentration is too low, bruising and bleeding may occur.
