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 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.

My 21-yr old orange boy is on a thyroid pill and has healthy bloodwork, but has lost a lot of weight last few years. We’ve went through nearly all types and varieties of food. Finally have landed on something he will eat consistently (for now) - fancy feast chopped grill canned and this. I mash up the chopped grill in a bowl with 1/4 can of water and a scoop of this. It feels like a win, and he’ll eat 1/4 in the morning and a few smaller times during the day, then 1/4 at night. He has dry available (science diet and fancy feast) but this combo is working for now. Not sure it really adds weight, but at least helping get him to eat.

I have two 17-year old girls. I noticed they started loosing weight, their ribs and backbone became very prominent. The hair was matting, no matter how often I would brush them. It is not my first rodeo, so I started getting ready for inevitable. After three months of adding this stuff to their wet food, they both gained back almost all the weight, their long fur again is shiny and thick. They started grooming themselves again. Yesterday I found their old laser toy. The two were running around and jumping like kittens, scaling walls and ended up on top of my wall unit. Try it and I hope it does for your babies what its doing for mine.

I bought this to try to help my kitty gain some weight back, she's been losing it due to seizures. I have put this in her dry food, in her wet food, I followed the advice in the instructions and made it a gravy and I tried it just the gravy, when she didn't eat that I put the gravy over her dry food, when she didn't eat that I made new gravy and put it in her absolute favorite wet food that I've never seen her turn her nose up at for anything. Nothing! She will not eat anything this is in, even just a half scoop trying to mask it. Don't buy, they just walk away. This cat has never ever turned her nose up at anything, I've caught her eating straight up garbage but even she won't eat this.
