My cats love this!
I have had several cats that have benefited from this product. From aged kitties nearing the end of life, to cats fighting off infection and needing a boost to their appetite. They all love it! I always keep it on hand... just in case.

Cat likes it
I found a cat who is only skin and bones. He has no interest in eating at all until I added this gel to his food. He likes the taste and he’s eating a little bit rather than before when he wouldn’t eat anything. I’m hoping this helps him and he gets a chance at life. He’s just a baby and he’s deadly skinny. He loves this gel stuff so I recommend it because he’s eating. I haven’t seen wait gain in him but he’s also barely eating. Hoping for a miracle.

I highly recommend this product to anyone who has a kitty that is not feeling well. My senior cat has been sickly due to upper respiratory problems, so I took him to the vet. He was given an antibiotic injection, but still seemed sickly 2 weeks later. I bought this high calorie booster and I kid you not, that very night after giving him a half teaspoon of this, he got his appetite back and gobbled up his food, he started having energy, acts like a young kitty. He even looks better. He loves the taste too, so I don't have to fight to give it to him. Try this if your cat is sick. It's worth it to see your furry friend come back to life!

Great option for picky or sick cats
My 7month old cat is the pickiest of picky cats. He wasnt eating and then he got a cold. I used the trick suggested of putting some on top of paw and he LOVES to lick ot off. I instantly noticed his boost in energy?

It is worth a shot!
After the cat diagnosed with thyroid issues (who it was for) wanted nothing to do with it...I tested it on our menagerie of was very random who liked and disliked it.

Very satisfied
Great product! I had a very sick kitty with pnemonia and he had not eatten on his own for five days. I continued to syringe feed baby food, which didn't harbor many calories or vitamins. I gave my baby a syringe of this and within an hour and thirty minutes he was up drinking on his own and managed to use his litter box. He was so weak he would barely walk. I seen a huge improvement right before my eyes! As for people complaining about their cats not eating it on their own, don't be lazy use a syringe if they need vitamins!
