Review: It works, 1 week result - This supplement is effective. After just one week of use, I could already see a difference. The photo comparisons show improvement every day, and my kitten looks much healthier now. She is almost 3 months old, and so far I have not seen any side effects.
Review: Great product - My rescue kittens were fully vaccinated, yet still contracted panleukopenia. While they were so, so sick and unable to eat, Under the Weather gave them nutrients and the energy to fight and survive. I am keeping a tube on hand for any future emergency.

### ⭐⭐⭐⭐⭐ Highly recommend
*by J***E on August 3, 2025*

We had a stray kitten that my daughter saved she almost ran her over. After she got her spayed which she was about 2 months she got very sick with respiratory infection .she was given antibiotics but still would not want to eat so we had to force feed her which was very hard she would spit it out mostly. I was given other food substitution which was not working..so I read on these reviews and decided to try it due to all the benefits it has. Surly that next day she started eating on her own. She is so small and was barely surviving very boney..now she loves to eat and has a great appetite..I'm still giving her this because although she's eating more like very well she's still pretty small. This really helped so so much. I'm so happy and grateful to this medication and of course God..I highly recommend to get this my kitten didn't have much hope according to the doctor she was super weak. She wouldn't eat she couldn't meow and always slept didn't have energy to walk around. She is now about 4 months but is the size of a 2 month but is now stronger and more alive. Her eyes and face is so much different as well. I like it because it's restore is like peanut butter so I put it in her mouse and she has no choice but to eat it she can't spit it out.
