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.

My cats kidney function improved significantly since we started using these supplements.

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!)

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!

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.

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

Good product

2024 edit (7 years later) For anyone reading these reviews, my kitty lived to 21 years old with the human supplement vs feline. Unfortunately nothing is miraculous, but it certainly helped compared to the feline version. (Original review) I previously left a rave review on standard process renal for humans. Amazon went through a period of time where that was not available. My 16 yer old cat has had human renal crushed and mixed into her can food everyday since over a year ago when the vet first identified her reduced kidney function. Her lab results actually returned to normal on the human renal formula. When I received the feline pills and tried to crush them, I noticed a difference immediately. The feline pills are more cohesive- almost damp. They do not crush as easily. Once you crush them, the powder re-solidifies. It sticks to the spoon in chunks whereas the human formula does not. Additionally, they smell different to cats. My cat would avoid food with this mixed in. Thankfully, human renal again became available and my cat is back on track. I have an almost full bottle of these pills that are pretty much worthless at this point. Disappointing, given the cost. If you are considering these, I recommend the human version. Especially if your cat needs it and needs to eat his/her food. I'd be more hesitant leaving this review if I didn't have definitive lab results to substantiate my cat's behavior. Would like to caveat a thank you to standard process for making the human renal supplement. I'm sorry my experience with the feline version is negative, but you can't explain to a cat what they should like.
