I’ve been using this product for a few weeks now, and I’m really impressed with the results. My cat had been underweight and struggling to maintain a healthy weight, but since starting this supplement, I’ve noticed a steady, healthy increase in her weight. She seems more energetic, playful, and overall healthier. The product itself is easy to use — it mixes well with food, and my cat doesn’t mind the taste at all. I appreciate that it’s formulated specifically for feline nutrition, so I feel confident giving it to her daily. The instructions are clear, and the recommended serving sizes make it simple to monitor progress without overfeeding. Overall, this has been a game-changer for my cat. It’s helping her regain weight safely and steadily, and I feel good knowing I’m supporting her health in a manageable way. I highly recommend this to anyone whose cat needs a little help gaining weight or improving overall nutrition.

My cat's been fighting with stomatitis and he had lost a lot of weight. I'd gotten this stuff out of desperation to try to get him to eat more and maybe gain some weight. I took it with me to the next vet appointment and showed the vet. He was reading the ingredients cuz he was looking for certain things. He approved it and said to keep giving it to him. So right now I'm adding it to his food cuz he's now eating better after getting some treatment at the vet which he seems to be looking a little better so for now I'm going to say this is a good product. Of course it's also easy to use which helps.

This is a good supplement. I have a fussy 9 y/o who's had pancreatitis for a couple of years. Her weight tends to drop too much because she isn't really food focused. Sprinkling this supplement on her food gets her interested, and I know she's getting her nutrition. Her weight is up and this is part of her success story!

All my cats love this product! They definitely eat less when I forget to sprinkle it on their food. I told our veterinarian about it. He said that they are always looking for a good appetite stimulant and he was happy with the ingredients.

My cat refuses to eat now, sucks because I was hopeful but no matter what I do she will not eat it. Expensive, not worth the gamble.
