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.

I got this for a 7 month old kitten who seemed to lack interest in food and wasn't at a healthy weight. I tried all kinds of food, treats, supplements, etc. but he just wasn't interested. He was healthy, vet checked, and playful just skinny. I finally saw this and decided it was worth a try and amazingly, he LOVED it mixed with his canned food! Within a couple of days he was cleaning his dish after every meal and by the end of the month he was up to a good weight, his coat was getting shiny, and he just looked 'brighter'. I've been adding some to the wet food of a couple young females and their coats are already looking so much better. I hadn't thought they looked bad before but they look gorgeous now.

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.

My senior cat refuses to touch his food with this powder on it. It also has a weird vinegar smell? Can’t say I blame him. I tried topping his dry food with the powder, tried it again with wet food, mixing it with water etc. Nothing seems to work. If your cat is picky eater, I recommend the wet tubes this brand offers instead (the ones that look like syringes). I’ve used those in the past and they work really well. It’s just they only have them in single packs, I was hoping this would be a good replacement, but it was not.

I have a 19 year old Calico cat. She was eating and drinking normally but I noticed she was losing weight fast. I know it's due to age but I wanted to try to help her. Bought this product and let me tell you... she pushes my hand out of the way when putting down her raised food dish! I sprinkle just a bit on her pate food (vet said she a has "grandma teeth" and can't eat the Blue Buffalo dry food I feed my other cats). She loves it! I'm just trying to do right for my grandma cat who I've had since she could fit in the palm of my hand. I introduced it to her slowly, not putting too much on her pate each time I feed her. After several weeks, she has a bit more spunk in her! I'm excited that she likes it so much and I'm really hoping it helps her gain weight.
