Researchers from the University of Nottingham have uncovered a surprising biological quirk in domestic cats that may help explain why they are so prone to chronic kidney disease. Unlike dogs and most other mammals, cats appear to accumulate unusual fats inside the cells of their kidneys, sometimes from a very young age. This new study, published in Frontiers of Veterinary Science, and led by Professor David Gardner and Dr. Rebecca Brociek from the School of Veterinary Medicine and Science at the University, shows they are anything but ordinary.
