Great supplement
I have a cat who has never eaten cat food. Crazy!!! But I've had him since birth and I created the monster. Lol. I've been using this product for about 4 years now. I noticed he was not growing and his limbs were not acting right, I think it's because he wasn't getting the nutritional values because he didn't eat regular cat food. So I mix this with his chicken. I boil the chicken, cut into cubes, and mix in a Ziploc with this liquid supplement and he has not only grown, but has no abnormalities like stiff limbs, tiredness, etc. This has actually been a lifesaver for my little pal. No odd smell, texture is smooth and light, and it just tints/appearance the chicken a slightly darker color. 1 bottle lasts about a week and he has it on every serving of chicken which is about 3 times a day. I think but not 100 that it has a chicken flavor...Lasts well in the fridge and I will forever be grateful for this product. I don't think he would have such a good quality life if it wasn't for this vitamin supplement.

Good Product, But Have Delivery Concerns
This appears to be a good supplement. My cats are extremely fussy eaters and I was concerned they may not be getting optimum nutrition. After adding this to their diet, their coats are beautiful and energy levels are good for 16 year olds.My concern is with how the product is delivered. You don't know who the carrier will be until after ordering and sometimes not until it's received. UP trucks are not air conditioned, so I can't be certain the product will not be compromised if ordered in the summer, especially here in Florida. Wish there was a way to know before ordering, I don't want to spend the money to receive a product that may be damaged by heat and won't benefit my pets.

My cat has made great improvements!
My cat is one who walked up to me outside just emaciated and we took him in, to the vet. Even though he's healthy now after yards of medicines to clear a ton of infections and worms at first, he is still not eating as much as he needs to put on a little bit more weight. I decided to try vitamins to increase his appetite. This is so easy to give him. We use a syringe (one person holds and the other person pries open his mouth and ejects liquid vitamin). He was a little confused at first, but he kept licking his lips. He hasn't put up any fuss at all since the first time about taking this. He doesn't open up his mouth for it, but he is a willing participant and doesn't fight it at all. And, low and behold, his appetite has improved. He looks so much healthier even tho he's still a skinny cat. But he's playing with the dogs and running around the house non stop. So, he's feeling pretty good, I'd say. The bottle is going to last a long time. So, that makes the price very good. Just remember to refrigerate the bottle once you open it. This is good stuff and I'm so glad to not have to try giving him pills. Recommend (my friend bought a bottle after asking me where I got it and she's having results even better than me).

Too soon to tell.....
Too soon to tell if this is helping my cat. I had also found "Rebound" for cats/dogs on here and ordered it as well. She's currently taking the other one since it expires in 7days after opening. Did notice that both products have similar ingredients so didn't want to overload my kitty with vitamins etc. She hates both. But she doesn't eat soft food, refuses to, so liquid in a syringe by mouth isn't her favorite thing. Only giving three stars because it's too soon to give an honest review. Will update when she's back on it.

Yum yum yum!
My rescue cats and kittens love this stuff and beg for more! I can hardly believe it. To me, it smells like vitamins and I thought they’d hate it and I’d have to force it on them, but no, they lap it up right out of a dish. My rescue kittens come to me frail and dangerously anemic, malnourished and dehydrated from fleas, worms and diarrhea. I need to boost their nutrition all I can. This product will be my go to stuff. I’m thrilled and I hope it contains all the good nutrition it says it does.

Refrigerate after opening
Refrigerate after opening should really be prominent and highly visible on things you wouldn’t think are perishable. I couldn’t tell you if it works or not because I realized my mistake and threw it out.
