My seven year old fur kid was diagnosed with calcium oxalate crystals this past July. I hated to pull her off of her Fromm’s Whitefish and potatoe but I put her on Royal Canin Prescription Diet for crystals. We brought her in one month later and had her checked again and no crystals. She loves the food and seems healthy happy. I hope I never have to deal with stones so so far happy with a Royal Canin. In fact I tried to talk to Science Diet on the phone and could never get through. I called a Royal Canin and they were so helpful. I have to buy the food through my vet and in fact this food is also for struvite crystals too. I hope your little baby gets better I know I have had little pees in the bed and on the carpet. My fur kid felt really bad and we love her everyday . I will always be at her side taking care of her. Those crystals can be very uncomfortable and they can not help their little accidents. Susan |
