July 7, 2013: Polycystic kidney disease (PKD or PCKD, also known as polycystic kidney syndrome) is a cystic genetic disorder of the kidneys. There are two types of PKD: autosomal dominant polycystic kidney disease (ADPKD) and the less-common autosomal recessive polycystic kidney disease (ARPKD). It occurs in humans and some other animals. PKD is characterized by the presence of multiple cysts (hence, "polycystic") typically in both kidneys.
Chronic kidney disease, a leading cause of death in most domestic cats, happens when her kidneys are gradually and irreversibly deteriorating. http://healthypets.mercola.com/sites/healthypets/archive/2012/08/06/kidney-disease-in-cats.aspx
