Review: Great for Cats Helps with older kitty- - This product has been great when you are trying to get a new rescue or a rescue who is under the weather or waiting a day or two for a veterinarian appointment. Our older kitty had started to lose some weight and as a concerned cat parent, I was worried about everything from teeth to the change in weather. We have had a lot of rain, and though he is an inside kitty like a person he can feel when it rains. I use this anytime there is a significant change in our environment. I usually put a little in his wet food, but he will take it from the tube. Gives him a pick me up of energy!
Review: Soft solid food gel - One of my cats was recently diagnosed with IBD last year. A recent flare up was further diagnosed as pancreatitis and almost killed my smallest cat who was not very big to start with at 5.5 pounds. She quickly lost weight to 4 pounds. Along with other measures (soft bland diet, assisted to eat 2-3x daily, electrolyte water for dehydration and medications from the vet) for her recovery, this was used. I had looked into several high calorie emergency supplements and this was my choice for desertcart reviews, disinterested 3rd party information and price & quantity of product. In the past month she has put 7/10 of a pound back on. I sincerely believe this played a large part in her recovery and maintaining her current weight. I will buy my third+ tube soon to get her back to 5.5 or better. She was not overly happy about having to eat but did not mind the flavor. It smells like wet cat food. Not my choice of flavor but she was okay with it and that's what mattered. She has a little ways more to go but is much improved and is more like her old self. It is easy to dispense, not unlike squeezing a tube of caulking.

### ⭐⭐⭐⭐ Ok for my ederly kitty
*by L***C on June 24, 2026*

My cat is 16 losing weight I know time is near she eats but can go without eating I didn't have anything to lose. I bundle her in a kittie burrito and put a long sliver on my finger and put it on roof of her mouth. Been daily for a week. While I'm not too hip on ingredients her fur is really shiny soft so grooming has been easy for her. I just saw her lapping up water and she still seems interested in food. Long term no but for now I would recommend
