An infectious disease of the cat caused by ''[[Mycoplasma haemofelis]]'' which until recently was known as ''Haemobartonella felis''.

The organism is found on the surface of [[Erythrocytes|erythrocytes]] and is considered an opportunistic infection that causes illness following predisposing factors. It is possible to be transmitted via bite wounds, biting arthropods, via blood transfusions and from a queen to her kittens. The organism causes a cyclic parasitaemia in affected cats and infected animals despite mounting an immune response will become carriers of the organism.
