Could there be a link between your area’s water supply and your cat’s urinary problems? Pet-insurance provider Trupanion recently analyzed data from its claims to test a hypothesis that drinking water could be a factor for common urinary issues, including urinary tract infections, cystitis (inflammation of the bladder), urinary obstruction, and crystalluria (crystals in the urine).

Using data and reports on drinking water quality, Trupanion compared its claims data for urinary health conditions to U.S. regions identified by the Environmental Protection Agency as having higher hard-water ratings.


According to a report posted in Trupanion’s blog, “Male cats specifically, living in areas given an ‘extremely hard water’ rating by the EPA, had a much higher incidence of urinary health issues — especially crystalluria — and were three times more likely to have urinary complications compared with male cats living in areas with ‘slightly hard, ‘hard’ or ‘very hard’ water.”

Although Trupanion’s analysis of its claims data has not been published in a peer-reviewed journal, it’s worth consideration and does seem to suggest at least a link between hard water and urinary problems in male cats.
