Review: SAVES LIVES on our farm where we frequently rescue sick kittens - Because of our rural location people frequently dump cats near us where often the pregnant momma kitties make their way to our farm to have their kittens. Because of our unique setup with an auto feeder loaded with premium kitty food, the momma cats usually move their kittens to our enclosed catio when it's time to teach their babies to eat solid food thereby making it easier to catch and tame their Littles. Often there's one or more runts or sick kittens in most litters so we keep a fresh unopened tube of this Under the Weather on hand especially during Kitten Season. We've found almost every kitten has found this tasty treat absolutely delightful - after a small dab on the lips, they then willingly lick or nibble off a small squeeze until their tummies are full. By the 2nd or 3rd time they've had Under the Weather they regard us as safe creatures and no longer run allowing us to readily pick them up, they actually seem to look forward to getting this nutrient booster as a well deserved treat. If there's a really sick kitten we put a small amount of this Under the Weather and extra vitamin B1 thiamine in a bit of red cap whole milk, syringe feeding if they're too weak to drink themselves. If they have a bit of gunky eye we also add a dab of l-lysine powder. When they're 4 weeks of age we also treat with Baycox ie toltrazuril 10% then we repeat the toltrazuril 10 days later, especially if they've had diarrhea at all. Using this as our farm kitty rescue "protocol" we now save nearly 100% of the kittens who we can get our hands on. We re-home as many as possible, the rest are fixed and remain in our farm cat colony. We've been using Under The Weather for several years now - EVERY tube has been top quality and has definitely been vital in our effort to save lives; even kittens our vet was convinced no way would survive let alone thrive are now healthy active stout 12-15 pound farm cats. We have one cat who initially was a sick baby no one thought he'd survive, he was doing great until a farm accident, now as a tripod he's once again a strong agile kitty who readily scales trees and hay bales with only 3 legs. Everyone is amazed at his mobility and his vibrant health - again, Under the Weather definitively made the difference in his life, both as a kitten and as an adult recovering from a nasty infection developed within his deep lacerations prior to him literally dragging himself home for amputation surgery. ALL rescues, rehabs and farms should keep Under the Weather on hand to use for the sick or weak furballs. I'd give far more than 5 stars if possible, cannot recommend enough!
Review: She Loves the Taste and is Finally Gaining Weight! - Amazing for weight gain in senior cats! My cat has an overactive thyroid and was extremely frail despite being on medication. Since adding this gel, she’s finally putting on weight—her hip bones and spine aren't as visible, and she looks much healthier. She loves the flavor and eats it readily. Highly recommend for anyone struggling to get their senior pet to gain weight. I'll update this after her next vet visit late January.

### ⭐⭐⭐⭐⭐ This saved my baby's life
*by A***E on December 23, 2025*

Absolutely amazing product, my cat hasn't eaten or drank anything in 2 days and she was looking BAD. I was about to take her back to the vet when they opened at 7am but this was delivered at midnight so we gave her a dose (watered it down with warm water for easier dosage in a syringe into the mouth), sure she didn't like it but she immediately perked up and got enough energy to walk around! It's been almost 30-35 hours since she's had a dose and she's doing WORLD'S better. This and her prescription are working amazing for her. I'll 100% be buying this again if my baby's are ever sick and recommending this to friends <3 my vet said she loved that I bought this and was very pleased it worked for her.
