My cat has FIC, discomfort, and anal gland issues. What diet helps?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 9 years and 2 months old | 10 lbs

For cats with FIC, what is the best diet? I’m am giving her C/D wet with fish oil and kibble,but she still shows signs of discomfort. I wonder if the fish oil is throwing off the pH of the diet. Her symptoms are licking the urethra and obsessive grooming that occur sporadically it seems. The kibble is actually half C/D and half Royal Canine Adult Indoor. The high fiber in they kibble prevents her from getting anal sac abcesses. Thank you for your help.

I hate to hear that Lulu is having issues with FIC. It is a very common condition in cats. When you are feeding any of the urinary diets, you must feed that diet exclusively. The diets are generally designed to affect the acidity of the urine as well as stimulate drinking. When you mix the diet, those properties are negated so they don't work. I would recommend to feed a diet made by Royal Canin that combines Urinary S/O and Calm. It's a multifunction diet. The S/O will control the urinary signs and the Calm actually helps relieve stress. As you likely know, FIC is in part related to stress. Once you start the diet, it will take about 1 month to take full effect. For her anal glands, you could try a product such as Glandex to see if that helps control her anal sac issues. If the issue continues, follow the recommendation of your vet as far as testing her urine for infection. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
