Standard Process Inc. Feline Renal Support - Cat Supplement to Maintain Kidney & Urinary Health, Cat Supplies with Whole-Food Based Ingredients, Feline Supplement to Aid Renal Function - 90 Tablets

Standard Process' Feline Renal Support, combined with a low phosphorus and low protein diet, has really made a difference in my cat's quality of life. She no longer vomits and her stool has gone back to normal. Highly recommend it.

Standard Process is amazing for my cat, it has made a difference immediately! My cat had went outside for summer 2025 and got back not feeling so well. After trying other products, This is one that's actually truly working! Thank you for all that you do! I appreciate it so much! I'm overjoyed of how it has helped my cat! Maxi is feeling much better, Thank you!

My Archie was diagnosed with renal disease. He had gotten skinny and would vomit a lot. The vet suggested giving him this supplement, and wow it is like night and day the way his health improved after he started taking it. He went back to his normal weight, he stopped vomiting, he's doing great. He seems to love the taste so it is very easy to get him to eat the pill. I will probably be giving him this supplement for the rest of his life, but it is totally worth it.

I have used this product for years with my cats and have always had good results

The tablets are kind of big even though they are chewable.

I use Standard Process supplements for my entire family. They’re AMAZING and they help heal so many different ailments-even those that your doctor will tell you are impossible to heal. Mr Nacho is our 9 year old fixed male kitty. Right around Christmas I noticed that he was getting skinny and his behavior seemed off. Before I had a chance to take him to the vet he was trying to pee, but it was apparent that he couldn’t, as he was trying to urinate in any vessel that was in front of him. I happened to have this product as well as Kidney Gold and it worked overnight-he could pee again! But we weren’t out of the woods yet. He refused to eat these items mixed in with his food, so it was a bit touch and go for a bit before I became wise and started administering it thru a syringe. I also added chicken baby food to the mix to give him a little extra something to help fatten him up. Within a couple of weeks he was well enough to play outside again. I gave him one pill along with Kidney Good twice daily, and eventually added Epaktin to the mix. He never went to the vet, but to be honest I had to make an executive decision. I know that if I took him in they would have suggested I put him down. He had sunken eyes, barely moved-Mr Nacho was a mess. It’s now nearly three months later and he’s catching mice and birds again (he actually caught a mouse three weeks after escaping death). He’s now on a renal diet and doing quite well. I feed him the Tiki brand Silver food.

I don’t typically write reviews, but I’d like to bring others hope. This supplement helped save my 16 year old cat’s life. He crashed out of nowhere one day. We went to the vet and he was diagnosed with kidney disease. It was so advanced the vet didn’t know if their treatment would save him or not. I ordered this that same day and it arrived the next. They hospitalized him during the day for 3 days. I crushed this up and mixed it with a Delectables Squeeze Up and Kidney Gold each morning before he went to the vet and each night when he came home and fed it to him from a spoon. Each day he looked a little better and better. On the third day, they ran his labs to see if the fluids were helping. His kidney numbers had actually increased despite his obvious improvement so we were shocked. They sent us home with subcutaneous fluids to do daily. We continued to do that along with his kidney supplement mixture for 10 days. He was doing so well at the end of 10 days that he only needed fluids twice a week. We’ve continued his kidney supplement mixture twice daily the entire time. It has been a month since his first bad day and each day he is better and better. He is much more social than he’s been in years. I haven’t had more labs done to know exactly what his kidneys are doing, but I am so grateful for his improvement and I know this product has a lot to do with it!

This is such a game changer. My cat’s creatine, bun, and sdma levels dropped to non kidney disease levels on this!!! We started a year ago and he just kept improving. I’m so grateful. We give this once a day one tablet. He’s 9lbs and 6 years old. We also give standard process whole body and enteric support 2x a day each. He loves the taste… watch the video :) (to be fair he will eat anything though, but my other cat likes whole body supplement too!)
