I had two cats -at two seperate times-require trips to the emergency room for urinary tract problems. One of those times there was blood in the urine. The vet recommended a food especially for urinary tract health. So now they all (7) get Purina One Urinary tract dry food for breakfast and dinner. They also get 2 tablespoons of very diluted wet food (think soupy) with dinner. Bedtime treats are Whiskas dry.

So far, no recurrences.
