Prescription urinary diets are evidence-based welfare tools for cats prone to urinary disease, preventing painful and life-threatening obstructive episodes.
Prescription urinary diet management prevents recurrent painful urinary episodes that cause significant suffering in susceptible cats. Cats who have experienced urethral obstruction, struvite dissolution, or recurrent idiopathic cystitis benefit from dietary modification that reduces recurrence risk. The welfare gain from prevention exceeds the welfare cost of dietary restriction to a prescription formulation. Owner compliance is the primary challenge: maintaining cats on a single prescription diet requires motivation and practical management strategies particularly in multi-cat households. Cats who resist prescription diet palatability need gradual transition rather than sudden switch. The combination of dietary management and stress reduction addresses the full welfare picture for cats with recurrent urinary disease.
