Vet Approved - Miracle Goop
Fantastic product. FIV+ cat, tought to feed, this has boosted energy, increased vitality/health, put some needed weight on. Vet said that "whatever you're feeding him...keep it up!" This is a life-saving product.

Saved our sick cats life!
Our cat was starving because she has cancer and can't eat. We got her this product and she eats it! She will live to see her surgery which will only be because she didn't starve to death due to this wonderful product! She wants to eat but feels so sick, she's eating most of this tube. Please buy it for your cat if they are sick or won't eat.

Great product!
We have a cat that is 18 years old and had part of his lower jaw removed 4 years ago because of cancer. Due to this, he has a hard time eating. Summertime is hard on him and he looses a lot of weight. This product has given him extra calories and made him hungrier so he has not lost as much weight this year. I don't know if he would have made it this year without this product!

Great calorie supplement
Used regularly with a senior cat who needs to gain weight. She likes the taste and is gaining weight. Mission accomplished.

Really Works!
My 12 year old cat started having kidney trouble and stopped eating almost completely. I started giving him this supplement to get him to, at the very least, stop losing weight. After he finished the first tube I saw a great improvement in his coat and his appetite. Now I can barely get him to stop eating and his energy level is back to the way it was 5 years ago. He won't eat it by itself but I add it to his food or treats and he doesn't mind. I have reduced the amount that I give him to about a tsp. a day because, like I said, it seems to make him more hungry. He is currently still gaining weight and I couldn't be happier to have my cat back.

My cat loves it!
I have an elderly cat with hyperthyroidism, who, despite being fed every 2 hrs, is very thin. She's also VERY finicky. I found this product at a local pet store, and though I doubted she would eat it, I purchased it as I'm desperate for her to gain some weight. To my surprise, she LOVES this gel! I use it as a reward when she gets her meds twice daily, and also add some into her food during the day. If there's a food she's not crazy about, rather than throw it away, I mix in some High Calorie Booster in, and she usually finishes it! She also had a bad problem with vomiting hairballs daily, as this finicky eater won't eat ANY hairball treatments. This product is apparently not intended to help with hairballs, but she hasn't expelled a hairball for two weeks now. What a pleasant "side effect"! This product is not cheap, is rather gooey, and I must say has not helped give her energy, but I'll continue to give it to my cat in the hope that she'll put on some weight and start feeling better.

previous review
Thanks to the previous reviewer i feel assured that i am doing the right course of treatment for my eldery cat who has just been dianosed with hyperthyroidism. I bought the product before the review because i trust the GNC label. After reading online about the product and the review i am glad i trusted my judgement.

so far so good
I was in a panic after I read one of the reviews below ( the one star review) where it stated there was high manganese but then I realized the amount of manganese mentioned on the packaging was the amount in a kilogram which is over 2 lbs. Once I figured it out and did the calculations I realized the amount in the product was not high at all and will give it to my sick boy again in five minutes. I had been giving it to him for 3 days but stopped when I saw the review. Since he is on the brink of death from not eating I am glad I can add it to his force feeding again. He has perked up immensely. He has pancreatitis and while I am unsure if this is a good thing for that , since he was likely to starve to death, I had to do something. All I know is he is running around making trouble again, and it has given him another chance even if he doesn't have long to live given his poor health and doesn't seem to want to eat anymore period.

Like Humans if we don't like something it's not 'bad'
I would've personally liked if there were samples of this or any other type of gel consistency (sp) to see if your cat will like it. Since my cat doesn't like human nor wet cat food and I'm more in a panic to get my cat to eat, I tried it. He didn't like it, so I had to put it on his tongue and paw to 'force' it.

It's cheaper than 700 bucks for the vet bill with "let's try this test to see what it is, if not that test then this one over here" I think it's stress, but I'm not sure now.

I WOULD recommend this to a friend, because animals are just like us. They have a personality, I really think that people forget this. "Cats love milk, fishy products!" Over-generation isn't always so, it's like saying everyone in this category loves chicken, it's not so.

I would say if your cat likes wet cat food and likes chicken flavor then maybe it would be a better idea.
