Thank you for contacting Doctors Foster and Smith regarding your question.
Doctors Foster and Smith does not carry Hill’s Prescription Diets at this time. We also do not carry a diet that is comparable to the Hill’s Prescription Diet c/d. The prescription diets are meant to be fed under the strict supervision of a veterinarian and are only available through your veterinarian. The over the counter diets that are available are not formulated to address the needs of animals with certain medical issues, such as urinary crystals and stones. We recommend that you continue to feed the prescription diet that your veterinarian has prescribed for your cat with urinary crystals.
You may also wish to discuss other options with your veterinarian for your other cat who may need a reduced calorie or weight loss diet. We also recommend that any cat that vomits more than twice a month be examined by your veterinarian.
We hope this information is helpful. Thanks again for contacting us.
Drs. Foster & Smith
