Is it counterproductive for our cat's urinary issues if we mix Hills c/d Stress dry food with non-prescription Purina Pro Plan (or One) wet food?

Thanks for reaching out. When managing your cat's urinary issues, it's essential to maintain a consistent diet that supports their urinary health. Hills c/d Stress is specifically formulated to help manage stress-related urinary conditions by controlling mineral levels to reduce crystal formation. Mixing prescription diets with non-prescription ones may dilute these benefits, potentially counteracting the food's purpose.



However, some cats benefit from additional moisture in their diet, which is found in wet foods. If Purina Pro Plan or One wet food doesn’t conflict with the specific needs of your cat's urinary condition — such as reducing crystal formation — it might be okay in moderation.



At home, ensure your cat has easy access to clean water and clean litter boxes to encourage regular urination, which is crucial for urinary health. Watch for signs like frequent litter box visits, straining to urinate, blood in the urine, or urinating outside the litter box, as these may indicate a serious issue needing immediate attention.



Because each cat's situation is unique, I recommend booking a video consult with one of us at Dial A Vet. This way, we can better assess your cat's needs and provide personalized advice tailored to their health condition.
