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: Helped save my cat. - Helped save my cat that was sick and not eating. My elderly cat was not eating and larthargic. She would not eat her favorite food and just lay down all day. She needed something in her sysytem so i ordered this. She would not eat it so i put a dab on my finger and put some on her nose and side of her mouth. She slowly licked it off. Was a little messy but it got some vitamins and nutrients in her till i was able to get her to a vet. She slowly got better and started eating normally again. She now loves this nutrient paste and gets excited when i grab the tube. Highly recommend.

### ⭐⭐⭐⭐⭐ SAVES LIVES on our farm where we frequently rescue sick kittens
*by J***L on August 9, 2025*

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.

### ⭐⭐⭐⭐⭐ Works wonders!
*by G***H on January 20, 2026*

This product works well. My tortie baby is 11-12 and goes through periods of constant vomiting. Once she starts, there’s no way back except meds. However, sometimes meds aren’t available or the vet has to wait. Or, in her case, I know it’s not emergent after going to the vet so many times and just knowing her body/stomach aren’t having it. After days and days of not keeping food down and being severely stressed as a pet owner, this paste healed my cat and my stress. She wouldn’t throw up on this paste and little by little, it allowed her to keep food down. Highly recommend this stuff for cats that need an extra boost and some calories.
