Scientists in China have found a feline morbillivirus (that's the family of viruses that includes canine distemper and human measles) that appears to be connected to a significant percentage of kidney failure cases in cats. Because vaccines can be made easily for morbilliviruses, and they work REALLY well, this could be a huge breakthrough in the actual PREVENTION of this common cat disease.
For so many years we have had to shrug and admit we just don't know when people ask what causes so much kidney failure in cats. Some cases are due to a congenital genetic disorder, but most were always just a mystery.
I am really excited by this news and hope it turns out to be reproducible research, and most importantly that a vaccine is swiftly developed. I have lost too many patients and cats of my own to kidney failure.
