Feline urine is typically metastable for calcium oxalate and complexation is affected by many factors. Increased urine water may help reduce saturation of crystal components but may also dilute inhibitors of crystal formation. This data supports that the dynamic nature of calcium oxalate precipitation testing provides additional information on the capacity of urine to resist induced crystallization which is not reflected in the traditional super saturation calculation. Elevated sodium content of foods influenced calcium excretion and appeared to lower urine resistance to induced crystal formation. Further study of the relationship between RSS and COT and long term risk for crystal and stone formation is warranted. cannula system that allows fluid flow in only one direction at a time.
