4. Royal Canin will pay for the analysis of canine or feline uroliths. Uroliths from other species can be submitted for testing but there will be a $50 charge for this service and we do not have suggested management protocols for other species. Please note we cannot accept samples from primates. 

5. Within five working days of receiving the sample, an analysis of the chemical composition of the urolith as well as a comprehensive clinical management protocol of the urolith(s) in question will be available on the Royal Canin Veterinary Portal and will be faxed or emailed to your veterinary practice. If you have any questions regarding the clinical management of a urolithiasis case, please contact the Veterinary Consultation Service at 1-866-567-7088 or submit a case consultation request on the Royal Canin Veterinary Portal.
