Pyruvate kinase deficiency is a rare disease in which an enzyme ‘pyruvate kinase’, normally found in red blood cells, is lacking. This means that the red blood cells life is reduced and as a consequence there is a reduced number of red blood cells circulating within the bloodstream, resulting in anaemia.
The anaemia is often mild and intermittent and it is possible that any clinical signs may not be noticed until the cat is elderly.
