Thank you for submitting your question regarding Speedy. If his veterinarian has recommended a prescription diet, then he should stay on one. Royal Canin Veterinary Diets Urinary SO, Hills Veterinary Diet C/D or Purina ProPlan Veterinary Diets U/R are all great choices to help prevent crystals in his urine. I hope this information helps!

    I'm sorry Paws has been having urinary trouble! You can do the best of both worlds! Hill's c/d has a canned food version, so you can feed him that. He will get the wet food recommend by the vet, but will also have the special c/d formulation to help prevent further crystals from forming. I hope this helps :-)
