Review: Stuff really works!!! - Let me just say, I don’t leave reviews often, but I had to this one time. My 1yoa Himalayan has a food allergy where if she eats chicken her herpes acts up. Her eyes get swollen and she becomes lethargic. I have a few cats so if I’m not quick enough with cleaning, and she grabs one of their kibble, the process begins a few days later. After numerous times going to vets/specialists, eye creams and most importantly fluids, they came across Under the Weather. This stuff peps her up immediately! When I see her eyes start to get red, she gets her meds and a dab of this stuff and she’s running through the house talking! No more running to the vet for lethargy, it really gives her energy and helps keep her hydrated. No stomach or litter box issues. I’ll never be without this stuff, it has a lot of vitamins and minerals and is worth having on hand. Good for the senior pets too. Very happy I found this product!
Review: Prayed for a miracle…this tube could be it! - I was praying for a miracle because my cat has some complex medical conditions (IBD, acid reflux and that triggers Pancreatitis if not treated in time). During her flare ups she is unable to keep food down (within minutes she will vomit anything she has eaten/drank) and that can lead to a lot of other side effects such as gastric upset/bleeding, tiredness, and dehydration. In the past she has had to go to the vet and each visit is a minimum of $2500 by the time all things are said and done. Obviously nothing can replace a vet visit when it is urgent but if you can get ahead of the problem before it gets to that I am on board because who wants to have their animal in a cage with tubes and needles while they are figuring things out. I know some people have complained about the smell or consistency but it is really not that horrible. I have smelled cat food far worse than this product. It has a consistency like a slightly thicker toothpaste just not quite as dense and the smell is almost like a smoky fruity combination. It was easy to use, just remove the little foil seal and squeeze the product out. I was able to put a small amount on my finger (pea size to start) and just put it on my cat’s upper lip. After that she licked it off my finger. I say do whatever works for your particular cat ti get them to take it. After her first 1/2 dose of the product and after having nothing stay down before that, I am so happy to report she has kept this down! It is the first thing she has been able to keep down! As far as I am concerned this could truly be a little miracle in a tube! My plan is to give her this over the next few days as her source of nutrition (as long as she is improving) and then VERY slowly reintroduce her food. I will still give her the gel paste in smaller amounts to supplement her until she is fully back to her normal eating. She has had zero side effects, seems to like the taste. Yes it is pricey but if it works to help your pet and also saves you a very costly vet visit it is way worth it! So thankful for this product.

### ⭐⭐⭐⭐⭐ Electrolytes for cats! Yaaay!
*by A***N on 29 May 2026*

I live in a hot climate. Even though I have the misters running during the summer, I still worry about the TNR cats. Well now I can stop worrying so much. This product performs exactly as described. I just followed the directions and mixed it with wet food. It’s so easy to use. They ate it and were not put off by the taste or scent at all. No side effects that I’ve seen. No one threw up, so the digestive issues are none. About the energy levels, one actually came up for pets and then jumped up on to my lap! So I believe they like it.
