Effective and Vet Approved Kidney Support
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.

Vital for Kidney Failure Kitties
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.

SAVING MY DOG FROM KIDNEY FAILURE
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!

Worth a try
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.

Best phosphate binder for CKD kitties
My elderly kitty with CKD needed to go onto a renal diet - and she wouldn't eat it consistently so the vet recommended Phos-Bind be used in her normal (non renal diet). Using Phos-Bind has helped me keep my kitty's phosphorous levels lower and I've been able to (very) slowly start adding in small portions of her renal diet. The amount of binder used is tiny so the container will last a long time, it's tasteless (I tried it) and easily mixes into wet food (for dry food I re-hydrate it and then put the Phos-Bind on it so it sticks and a little "gravy" can be created with a couple squished kibbles).

Cat won’t eat, if this is in her food.
I have a cat in stage 3 kidney failure. I could put the tiniest bit in her food and she knows and won’t go near it. However, it’s recommended by my vet, so it must be a great help. Good luck and I hope your cat will eat it.
