Could my cat's urinary diet for bladder crystals cause cancer?

Hello. The development of crystals in the urine is pretty complicated & not related to any one thing. Stress, diet, the amount of water consumed each day, & how Samie's kidneys deal with urinary waste products all contribute to the development of crystals. Sometimes there is even a bladder infection to add to the problems. So no, tuna does not cause crystals, & it takes more than a few days for the crystals to develop & start causing a problem. Based on the type of crystal present, placing a cat on a special diet can help correct & prevent further problems. Increasing the amount of fluids taken in each day can also flush out the crystals & we often recommend low sodium broths, stocks & tuna water to accomplish this. Find out from your vet what type of crystal is bothering Samie & see if a diet change would be appropriate for her. Thanks for using Petco Pet Education Center, formerly Petcoach.

Special diets like the Royal Canin urinary diet work by keeping the urinary pH at a good level so crystals are less likely to form. So by feeding treats this may have thrown off the urinary pH and caused crystals to form. For this reason it's recommended to only feed the prescription diet. Feeding an all canned version of the prescription Royal Canin diet may be even more beneficial in preventing crystals so if Nila will eat canned food I'd recommend the canned version of the diet. Blood in the urine can also be related to urinary tract infections and bladder stones. It sounds like your veterinarian may have ruled these issues out, but if Nila has not had a urine culture or X-rays of her bladder these may be indicated (especially if the problem persists).

High calcium is not very commonly found in cats on well-balanced cat foods. Potential causes for hypercalcemia in cats include lab error or lipemic blood sample, cancer, kidney failure, bone disease, hyperthyroidism, toxic exposure, supplements, among a few others. I would recommend that you follow-up with your vet about these possible concerns. The vet may recommend additional testing, including an ionized Calcium level, which more accurately evaluates the calcium in the body than total calcium on most in-house blood panels.

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!

An over the counter urinary care diet should be fine to give if you have concerns. I would also recommend regular yearly rechecks of urine with your vet as this is the best way to monitor Mushu for any changes that may need treatment or a switch back to a prescription medication again. If you do notice him having any issues again, a vet visit more quickly for treatment is best.

Hello. I am so sorry for your concerns about Sofia. The RC Urinary s/o is an excellent diet, but sometimes we see a difference in the various manufacturers of these diets. The first thing to do, & this is a good time to do so, is recheck her urine. After about two weeks on a specialty diet, there should not be any ( or at least very few ) crystals in the urine. If there are still a substantial number of crystals, & depending on if they are struvite or oxylate crystals, you may need to try another diet, such as the Hills or the Purina lines of prescription urinary diets. Another thing to consider is switching to a wet/canned diet. The substantial amount of extra water a cat consumes with the wet diet helps to significantly dilute the urine thus helping to flush out existing crystals & preventing the formation of new ones. Best of luck & thanks for using Petco Pet Education Center, formerly Petcoach.

Purina Friskies is a low/mid grade quality food and I would not be surprised if his crystalluria returns. He really needs a prescription diet such as c/d from Hills or a similar formula from Royal Canin. Your veterinarian should have this food available, or be able to send you to a store to purchase with a prescription. I have also had good luck using Crystal Stone Formula ( a Chinese herbal), but this is a prescription herbal. I would be happy to consult with you about this. I would recommend a prescription diet for at least 6 months prior to trying to wean off of it. If you absolutely CANNOT get a prescription diet, I would focus on a high quality, high protein diet, but NONE will dissolve and prevent crystals as well.
