About This Item

Details

RenaKare (Potassium Gluconate) Gel is prescribed to help correct low potassium levels in both cats and dogs. Potassium deficiencies are common in dogs, and theyre particularly common in cats. Your pet may lose too much potassium through his urine and through his gastrointestinal tract. Pets who dont get enough potassium through their food may also need a potassium supplement to help regulate those levels. This gel is easy to administer, and your vet may have you mix it into your pets food to help prevent any stomach upset.

We directly source prescription medications from manufacturers and wholesale distributors registered with the FDA and licensed by applicable state boards. Guaranteed genuine, and where applicable, backed by the manufacturer.

My cat hates it

My vet put my cat on this potassium supplement. It’s a thick gel and I’ve mixed it in chicken pate but then my cat doesn’t want to eat the food. I’m going to see

My vet put my cat on this potassium supplement. It’s a thick gel and I’ve mixed it in chicken pate but then my cat doesn’t want to eat the food. I’m going to see if I can find it in a liquid form. Meanwhile, I’ve tried melting it in a bit of hot water then mixing it in the food. However a liquid form would be a better solution. The potassium has definitely helped her to walk more steadily.

Declining quality

Our cat has been on this medication for 3+ years. Within the past few months, this product is no longer a “gel” and is more “liquid.” This has made administration

Our cat has been on this medication for 3+ years. Within the past few months, this product is no longer a “gel” and is more “liquid.” This has made administration IMPOSSIBLE. We used to be able to measure out this medication in a 1/2 tsp and scrape it to the roof of our cat’s mouth, but the new liquid consistency makes that IMPOSSIBLE. Product description claims that it is “palatable,” but my cat disagrees. We’ve resorted to mixing it into his wet food and covering with Churu, and now he’s not eating because it tastes disgusting. Super disappointed. Looks like I need to start looking into compounding pharmacies.

Not for my cat

She will not eat this in any form, no matter how I try to sneak it in. I think the texture and the scent were both issues for my 21-year-old lady.

Not a tempting taste

First time giving my cat potassium, so I went with the flavored option. He really was turned off by the flavor. I would buy the flavorless powder next time.

Too thick and sticky to mix

I had to buy this because they were out of my usual RenaPlus gel. The RenaKare brand is so thick and sticky that it clumps and can’t be easily or thoroughly mixed

I had to buy this because they were out of my usual RenaPlus gel. The RenaKare brand is so thick and sticky that it clumps and can’t be easily or thoroughly mixed with liquid cat treats; it breaks up into little globs that my cat hates the taste and texture of. Every day I had to give it to her, she refused to finish her dose. I recommend RenaPlus instead, which has the same dosing but a consistency more like thick honey instead of sticky gelatin, making it easier to mix.

A good product but my cat

It is a very good product but unfortunately my cat could not tolerate the potassium gel and this med had to be switched to a capsule instead.

Works great for our kitty

Our cat (blind, 5 years old) needed a potassium supplement after being diagnosed with hypertrophic cardiomyopathy. While she does a generally good job with taking

Our cat (blind, 5 years old) needed a potassium supplement after being diagnosed with hypertrophic cardiomyopathy. While she does a generally good job with taking medicine, we were a bit worried with how to give her a supplement. We have another cat and they tend to share food bowls and we also wanted to have a sense of confidence knowing she ingested most of the supplement. This gel has worked out great! We tend to rub her dose into her two front paws and she calmly walks over to a corner and licks it off. She doesn’t seem to mind the taste and she always licks all of it off of her paws. The only downside to this gel is that it does have to be rubbed in quite well or it stays in clumps which is easy for her to shake off. We do find bits of potassium gel in our apartment from time to time, but it’s easy to clean off with a damp towel. We laugh about the spots where we find it. Overall, we are very happy with this product as it has been a great way to give our little kitty her daily dose of potassium pretty much pain free.

No way

My cat would not let me dose him with this. He hated it, and it's so messy.
