My cat was diagnosed with calcium oxalate crystals and stones in her bladder. She will undergo surgery today. What is the best food/ type of food should I feed her after the surgery to avoid having this condition again?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am sorry you and Sanjee are going through this. First I think it important to wait until the stone analysis is back before deciding 100% what to do diet wise. Even though she has calcium oxalate crystals doesn't mean the stone will be that exactly, though it is likely. Calcium oxalate stones are the hardest to prevent recurrence. I recommend Veterinary Prescription diets like Royal Canin SO, Hill's c/d or Purina UR. I also recommend monitoring urine pH and concentration. Calcium oxalate crystals form in more acidic (lower pH) urine. If the diet alone won't control the pH and keep it more neutral sometimes we have to add potassium citrate. I think periodic X-rays to check for recurrence are also important. There are many small white dogs that have had many cystotomies to remove calcium oxalate stones. I hope this helps and I wish Sanjee the best today for her surgery and a speedy recovery!
