CATS THAT ARE AFFECTED BY PKD (POLYCYSTIC KIDNEY DISEASE), DO PROGRESSIVELY GET MORE AND LARGER CYSTS (LOOK LIKE EMPTY BUBBLES) IN THEIR KIDNEYS. THESE CYSTS REDUCE THE KIDNEY TISSUE AND THUS THE KIDNEYS’ ABILITY TO FUNCTION PROPERLY. GRADUALLY THE CAT STARTS BEING UNWELL, GETS THINNER, LOSES APPETITE. THE CAT DOES ALSO DRINK MORE THAN USUAL. IT IS POSSIBLE TO HELP THE KIDNEYS IN GIVING THE CAT A SPECIAL KIDNEY DIET, BUT THERE IS NO CURE FOR THE DISEASE.

PKD IS INHERITED AS A SINGLE AUTOSOMAL DOMINANT GENE. EXPERIENCED VETERINARIANS WITH GOOD EQUIPMENT DO FIND MOST OF THE CASES, BUT NOT ALL, WHEN THE CATS ARE ABOUT ONE YEAR OLD.

THERE IS A GENETIC TEST FOR THE MUTATION, THAT ABOVE ALL CAUSES MOST OF THE PKD CASES IN THE PERSIAN AND IN BREEDS THAT ARE RELATED TO THE PERSIAN. THE TEST IS DONE BY SENDING A SWAB FROM INSIDE THE CHEEKS (BUCCAL SWAB) TO ONE OF THE ACCREDITED LABORATORIES.
