I have been using this for quite a while now and I am currently on my fourth container. The vet is happy with it, the cat tolerates it without any issues, and that makes it easy for me to keep using it consistently. It does tend to clump when mixed into wet food, but adding a little water helps a lot and makes it much easier to blend evenly. Most importantly, my cat’s kidney profile is looking much better, which makes this feel well worth it.

Kidney failure, unfortunately, is so prevalent in old cats. It has taken many of mine over the years. None of my cats would eat the canned Prescription cat food, and it costs a fortune. We now add this to the regular cat food they like, and to the homemade cat food they like, with no problem.

I was told my dog was in kidney failure and to consider this hospice. He’s 17 but you jnow when you have “that” dog you’ll do anything for, thats him, i love him too much and so I searched and searched and I read reviews and I said let me try this out. And let me tell you this stuff is God sent my 17-year-old Italian greyhound phosphate levels were at 10.3 normal is to be below six. I started to give this to him at the end of August and now it’s November and his phosphate numbers are normal now the vet said I don’t know what you’re doing, but it seems like he’s reversing. His kidney levels are better his liver levels are better overall doing much better and I can’t be grateful enough.God bless this company!

UPDATE: Molly went back for follow up labs in September and her creatinine only went up by .01, so this product is definitely helping with the progression of her CKD! Our 9yo tabby recently got dx with early stage kidney disease. The cost of the Rx food is ridiculous, especially with many reviews indicating their cats don't like it. My vet approved us trying this and we've been using it since January. We mix it in with her wet food and add a little bit of water to make it kind of soupy so it mixes better and she hasn't (YET) noticed that there's anything added to her food. We aren't due for labs for a couple of months, but she seems to be doing a lot better since introducing this into her diet.
