Review: Effective and easy way to help my cat gain weight - 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.
Review: Great addition to your pet's food! - 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.

### ⭐⭐⭐⭐ Excellent supplement!
*by E***. on February 21, 2026*

This has been useful for a picky senor dog. The dog prefers it dry vs as a gravy. I mix it with dry food. They're keeping up their energy level and seem peppier throughout the day. I'll buy it again. The one thing I'd change is to have more guidance on serving sizes on the container.
