Product information

Anti-Diarrhea Liquid For Cats:  Having a poo-tastrophe? Our vet formulated Anti-Diarrhea Liquid helps to quickly firm stools and soothe your pet’s upset stomach. Tummy troubles are no match for Kaolin and Pectin, which help reduce gas and diarrhea by absorbing bacteria and toxins from the intestinal tract. Helps alleviate discomfort, irritation and cramping associated with diarrhea in cats. Manufactured without artificial flavors or dyes. Made in the USA. 

Probiotic Powder for Cats: Support your cat’s normal appetite, digestion, and immune system. Containing one billion colony-forming units (CFU) of live (viable) bacteria, when given daily, this easy-to-use probiotic powder supplement will aid in promoting and maintaining proper balance of beneficial bacteria needed for a healthy immune system. Veterinarian-formulated and manufactured in Vermont, our Cat Probiotic Powder is free of corn, artificial flavors and dyes, and has a great chicken liver taste your kitty will love!

A black dog with a blue collar sits beside a packet of dog food and a bowl.

muddypawsrescuenyc When he first arrived, he was in a bit of rough shape. He was found as a stray, so no one knows exactly what his past was like. All we know is that his future is as bright as his smile! After a few bags of @undertheweatherpet Chicken and Rice (which he gobbled up too fast for us to catch a good photo, yum!), and continuing medication for his stiff joints, Tavo is perking up and has blossomed into the most perfect gentleman.

Amazing results fast! Our Pitty was having a flare up and I decided to try this. He is now holding his leg up sturdy to pee again and has more energy it seems. I can definitely tell this product works! Definitely worth the money! Thank you!

olivemygolden The greatest product ever invented (especially if you have a golden that will eat anything ). I always keep some on hand & they always get used up @undertheweatherpet

We love it!

Finally found a powder for my picky eaters! My cats don't like seafood flavored anything. It was a great relief to find this product. They happily eat it mixed with their wet food.

Instagram User Thank you @undertheweatherpet for all the wonderful products! Being a foster/rescue mom 🐾 and having rescued an anxious and picky husky 🐶, I can really appreciate your products!


We have freeze dried bland diet for dogs (a quick food replacement when I’m in a pinch - and SUPER healthy for your dog), hemp calming treats for prone to stress pups, and (I know we don’t want to talk about it, but so needed!) anti-diarrhea to help firm up those loose poops 💩!


Skye definitely is an Under the Weather Pup!

No longer ‘Under the Weather!’ Our 15 year cocker, Peanut, has multiple issues and most foods make her so sick and unhappy. But now she is dancing for dinner again. Also, she gets happy when she sees the kettle boiling as she knows what’s coming! Thank you for making such a good product for fur babies.
