What non-prescription wet food for my senior cat's urinary issues?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | 10 lbs

I have a cat that is 16 or 17 with urinary issues. For about 3 weeks he’s been on RX Blue Buffalo WU. He didn’t like the canned food of that brand so only on dry. I’m still trying to find a wet food he will actually eat & not just lick the water from. He still has issues & I’ve noticed muscle spasms in the penile area. I don’t know if we need to try another food. Any suggestions that isn’t costly prescription food & is not full of carbs or other junk that he doesn’t need? Looking for help thanks

Without a full diagnosis of the actual health conditions it is almost impossible to advise on a suitable diet - kidney failure, urinary stones/crystals, urinary tract inflammation, incontinence and bladder tumours can all cause urinary tract symptoms in older cats and each require slightly different management - I recommend you contact your vet to discuss exactly what types of food are most likely to help Patches. When it comes to kidney and urinary issues however, high quality, specialist prescription diets are preferred as they are tailored to prevent progression and reduce severity of clinical signs and are worth the investment, even if you can only stick with them for 8-12weeks to allow stabilisation

    Yes, cats with kidney disease need a special diet, more frequent monitoring and possibly additional medications if they are losing protein in the urine. Some cats also benefits from subcutaneous fluids; Here is a helpful link about renal disease: https://www.petcoach.co/article/kidney-disease-treatment-for-dogs-and-cats/ I recommend the Royal Canin renal diets. Offer both canned and dry. I also recommend to discuss what treatment options are best for Tammy. I hope this helps and please feel free to post any additional questions.

    hello and thank you very much for your question. I applaud you for taking such a proactive approach to your cats health. The best recommendation I can give you to help prevent kidney disease is to feed a senior diet or a very low protein diet. The more protein that a cat has the more possibly toxic byproducts that can build up in the cats system when the kidneys are not functioning correctly. But before trying an over the counter senior food, I recommend you take your cat to the veterinarian to have them perform a CBC and chemistry profile As well as a urinalysis. Because if there are any issues with your cats kidneys currently, and over the counter food will not be the best choice for your cat. Instead, you will need to b because if there are any issues with your cats kidneys currently, and over the counter food will not be the best choice for your cat. Instead, the veterinarian will prescribe your cat a prescription kidney friendly diet and that will be vastly better than anything over the counter. Thanks a lot for your question. I hope I have given you some help today.

    Yes increase the amount of water and give specific diet for kidney problems (like k/d) would be ideal. The k/d diet is designed for adult/old age cats anyway so I would feed him normally until he's not at least 10 years old. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
