There is on going health programs within SVERAK to prevent PRA and PK deficiency in this breed, which has reduced the number of cats carrying this type of genes. PRA stands for hereditary degeneration of the retina that leads to blindness briefly described. PK deficiency is when there is a deficiency of a kind of enzyme that causes the red bloodcells to otherwise have a shortened lifespan that results in anemia (anemia). We breed carefully so that these diseases are not in our lines.
PK and PRA tests are registered with Sverak and are visible on their website. As a breeder, it is important to check that the parent you intend to mate are free from these two hereditary predispositions and backwards in the pedigree of previous parents aswell
