My girl suffers from crystals in her urine. The vet recommended Royal Canin 50 moderate calorie. It causes her to drink MUCH more water and consequently she now has to be let out to go in the middle of the night which she never did before. We previously had her on Science Diet CD which caused her to gain weight and didn't solve the crystal problem.
Does anyone make a suppliment or food that can address the crystal problem without these side effects?
