I've noticed lately with the passing of many RB persians that many have not lived as long as I expected for whatever reason. Our first persian, duchess, had just made it to 15 years before her kidneys failed completely. Our other persians are 15, 12, and 4. Is the life expectancy the same as any other cat or are they shortened due to the fact that they are more prone to illnesses genetically? Or does breed matter at all and just depend on each individual cat?
