Hi Christie:
Here’s a site I referenced when one of my furries had a life threatening urinary blockage.

I have fed Rx foods in the past and would do so again if needed. Most are not for long term feeding because they are specially formulated to address a health issue. Once the issue is resolved then you transition back to their regular diet if appropriate.
After surgery for the blockage I opted to feed an Rx food until I got an all clear from my Vet. The first food we tried did not go over well. Science Diet canned is what I ended up feeding for the duration of his treatment with success.
I don’t have any suggestions on your Vet’s recommendation for an OTC GF food.
Perhaps another option would be to get an Rx from your Vet to try a different brand. Along with Royal Canin, Purina has an Rx recipe for urinary health that is not high in calories and you may like the ingredient line up better. There are several on-line sites that sell Rx foods such as Chewy that has a great return policy. Google “pro plan veterinary diets”
One product I have had allot of luck using to entice my pets to eat during rehab is Purina Forti Flora probiotics. I am using it now for one of my cats that had a major dental a few months back and is still having health issues. He has continued to lose weight among other things. Sprinkled the Forti Flora on his food last night and he didn’t even let me mix it in. Just started eating like he hadn’t been fed for a week…yeah!! Maybe that’s something to look into. My Vet sells it by the packet or box for both cats and dogs. You can also buy it on-line.
Another option is to consult a Vet nutritionist for a homemade diet. I use Balance IT Carnivore Blend supplement for homemade meals. Balance IT provides excellent customer support and also does Rx food consultations with your Vet. Google “Balance IT”
This is a Vet nutritionist that will also do a food consultation with your Vet, Dr. Rebecca L. Remillard. You can find allot of good info in the “Nutrition Library” and “Ask the Nutritionist” sections. You can even ask her questions if you can’t find info on something you’re interested in:
