A continuing trend
On a side note, during the past 30 years, the number of canine urolith submissions has exceeded the number of feline urolith
submissions by a ratio of about 4 to 5. This continuing trend is surprising given that there are more cats living with families
in the United States than dogs living with U.S. families. For example, in 2011, we received 57,152 canine uroliths and 13,164
feline uroliths. This results in a ratio of 4.3 canine uroliths for every feline urolith that we received.
Editor's note: With the support of an educational gift from Hill's Pet Nutrition, as well as contributions from veterinarians and pet owners
worldwide, the Minnesota Urolith Center is providing quantitative urolith analysis at no charge. Online submission, email
notification and electronic retrieval of results are available. With access to our database of about 800,000 samples, the
veterinary community is offered the latest information on urolith trends, treatment and prevention suggestions. For details,
