The number of blood groups varies between the domestic species and are determined by the presence of antigenic components on the surface of the [[Erythrocytes|red blood cells]]. Cattle have 2 blood groups (B and J) and the most complex blood group systems while [[Blood Groups - Cat|cats have 3 blood groups]] and are quite simple. [[ Blood Groups - Dog|Dogs have 8 blood groups]], horses have 3, A, C and Q and sheep have 2 groups B and R.

Normally an animal will not have antibodies against antigens present on the surface of its own red blood cells or against blood group antigens of that species unless they have been produced following pregnancy, a previous transfusion or a [[Vaccines|vaccine]] reaction. However this is not the case for cats, who have naturally occurring alloantibodies.
In order to achieve a safe blood transfusion blood typing and sometimes crossmatching of the donor and recipient patient is required. Transfusion of the incorrect blood type can lead to a haemolytic transfusion reaction which can be fatal.

Giving blood components over whole blood is advantageous as it reduces the number of transfusion reactions and also allows specific replacement therapy.
