Pancytopenia is a bone marrow condition that causes rapid depletion of white blood cells, red blood cells and platelets. Given the importance of these blood cells, pancytopenia can become fatal if untreated.
The United Kingdom reported cases of pancytopenia in cats. Royal Veterinary College has reported at least 528 cases of this illness in cats. Nearly 63.5 per cent of these cases resulted in deaths of the felines. The possible causes may be toxins, feline AIDS, feline leukaemia, bone cancer etc. It is caused when the bone marrow stops functioning properly.
