Abstract
A cat food composition comprises ingredients that work to manage urine pH and urine saturation levels to treat or prevent urolithiasis. In some embodiments, a wet cat food composition comprises flaxseed, fish oil, calcium sulfate, methionine and sodium acid pyrophosphate (SAPP). In some embodiments, a dry cat food composition comprises fish oil, methionine, taurine and potassium sulfate. Flaxseed and/or fish oil provide omega-3 fatty acids to minimize urolith formation. Calcium sulfate, potassium sulfate, taurine, methionine and/or SAPP help achieve an ideal urine pH between 6.15 and 6.85. In some embodiments, the cat food composition is configured to establish an average RSS struvite value less than or equal to 1.8, and/or an average RSS oxalate less than or equal to 6.0.
