New research from the University of Nottingham has revealed that cats are different from other mammals due to their accumulation of unusual fats in their kidney cells. The study also revealed that the cells of the kidneys accumulate a rare group of modified triglycerides, which may explain why cats are prone to chronic kidney disease. The research could help identify the cause of this condition and potentially improve diagnostics and treatment options. If successful, experts may develop a strategy to prevent the accumulation of these fats and potentially help cats live longer.
