Urolithiasis in cats causes painful urinary obstruction and recurrent discomfort. Understanding stone types and treatment options helps owners make informed welfare decisions.
Bladder stones cause welfare problems ranging from chronic discomfort during urination to acute life-threatening obstruction. Cats with stones experience pain and dysuria that makes every litter box visit distressing. Partial or complete urinary obstruction causes extreme discomfort, systemic toxicity, and death within 24-72 hours if untreated. The recurrent nature of urolithiasis in predisposed cats means some animals experience repeated episodes of acute discomfort throughout their lives. Prevention through appropriate diet — particularly adequate moisture content and reduced mineral concentrations — is more effective than repeated surgical interventions and significantly improves long-term quality of life.
