• C. Horses
• D. Cows

Answer: (A)

Fat droplets in urine, or lipiduria, occur when lipids spill into the urine due to systemic lipemia or kidney handling of lipids. This finding is most commonly seen in cats because feline metabolism and disease patterns often produce hyperlipidemia that leads to lipid droplets appearing in the urine. Conditions like diabetes mellitus, nephrotic syndrome, or pancreatitis can raise circulating lipids in cats, making lipiduria a more frequent observation than in dogs, horses, or cows. In the other species, lipiduria is much less common in routine urinalyses and typically only appears with marked lipemia or specific diseases, so the feline presentation stands out on exam.
