My cat won't eat Royal Canin SO for crystals. Are there other options?

From Royal Canin's website: "This diet is only suitable for healthy adult cats that do not have a urinary issue or a history of urinary problems. This food is not a replacement for a diet prescribed by your veterinarian." If Elbi has already had a urinary problem, I don't recommend considering switching to the urinary care food. Urinary S/O is designed to encourage more drinking, as well as neutralize the pH of the urine - both of those together tend to almost completely eliminate the chances of crystals forming.

I would strongly advise against this. I would keep him on some form of food labelled for urinary crystal prevention. Urinary blockages can be a fatal emergency. Royal Canin, Hills, and Purina ProPlan are the three foods that use the most science in their nutrition. I have never heard of young again. Any of their foods that are labelled "S/O" are meant to prevent the formation of urinary crystals. Many urinary diets do have an increased caloric amount, and I sympathize that can be a struggle, but it is related to what keeps their urinary tracts healthy. You can try feeding canned food that is watered down to lower some calories. The extra water and hydration is great for the urinary tract as well. Feeding the food out of toys and feeders, instead of bowls in meals, to encourage their working for food and hunting behaviors can also help with their food intake.

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!

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.

So both are urinary diets, just make by different brands. Urinary SO is made by Royal Canin, and Urinary UR is by Purina. Both are formulated to help dissolve struvite stones and prevent their reoccurrence. I hope this helps.

Yes it is. That's because it helps dissolve crystals and has properties to increase urination and prevent further crystals from forming. If Coleman does have urinary crystals, I highly recommend feeding him this food.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I politely disagree with your Vet. I do not recommend over the counter urinary diets for cats who have been obstructed. It is a life threatening condition and not to mention expensive issue. I wouldn't risk a non-prescription diet. They are not comparable to the prescription options. I recommend, if your cat will eat it, an all canned food prescription urinary diet like Hill's c/d, Royal canin SO or Purina UR. Increase water intake where ever possible (adding water to the canned food, water fountains, etc). If you decide to go with an over the counter option then go with the lowest ash and do all canned food. I wish you the best!
