How long until I start to see the effects?

Answer by ChewyDec 21, 2021
Results can be seen right away as this product's primary purpose is to add calories when your pet is either not eating at all or not eating enough. In addition to calories added, this product also has the added benefit of vitamins and nutrients. This supplement can also act as an appetite stimulant.

Is this product safe for kittens?

Answer by ChewyJul 27, 2021
This gel supplement is is formulated for cats and kittens of all ages who may not be eating normally due to reasons such as, medical procedures, illness, or stress.

Can this be given to my cat with hyperthyroidism? I know some high calorie gels are hard on the kidneys.

Due to your pets specific health concern, we recommend consulting your Veterinarian to see what would be the safest fit for your pets current treatment plan.

My daughter’s little guy Ravioli was diagnosed with dry FIP at one year old. He lost so much weight in such a short amount of time, it was horrifying. This in conjunction with vet prescribed antivirals, appetite stimulant, liver support,, and sub-q fluids saved his life. Grateful for this high calorie treat and for chewy getting it to us promptly when we needed it.

My cat's immune system has improved and he's not catching colds as easily

P.C. is a 16 y/o cat and is having problems staying healthy. He is an inside cat and catches colds easily. We took him to the Vet, and she said he had lost a lot

P.C. is a 16 y/o cat and is having problems staying healthy. He is an inside cat and catches colds easily. We took him to the Vet, and she said he had lost a lot of weight and needed a supplement. In addition to the antibiotics, we started giving him a dose of Under the Weather twice a day, per our Vet. He's looking better, more active, and not sneezing or sniffling. He's even started climbing the little stairs to the sofa and cuddling with us again. I really like this product because it's affordable, it works, and P.C. is not miserable. Yay!

Helped through sickness

My puppy had Parvo and would not eat. However, she did love the taste of this product and was able to swallow it. The extra nutrition and calories helped her recovery

Not for Poppy!

I was hopeful that I could get a few extra calories into her, but this one is not working at all. I would give it to my other cats - they seem to like it - but

I was hopeful that I could get a few extra calories into her, but this one is not working at all. I would give it to my other cats - they seem to like it - but all of them are at a good weight and they don't need extra calories! So I"m in the middle on this one - but to be fair, Poppy is extremely picky!

I had high hopes

With so many positive reviews, I figured it would be a good idea to get this. She smelled it but she wouldn't try it. I know she is growing weaker and thinner,

With so many positive reviews, I figured it would be a good idea to get this. She smelled it but she wouldn't try it. I know she is growing weaker and thinner, so I try to hold on to her for as long as I can.

The ingredients and that they support appetite and gaining weight

My cat wouldn't touch a bite - and I bought two tubes. Now enticing her to eat with smelly regular cat foods and mousses by tiki cat instead.

Cats appetite and weight improved

Cat wasn’t eating well or not at all due to asthma / allergy symptoms. I mixed Under the Weather with a creamy treat and crushed allergy meds. He ate all of it

Cat wasn’t eating well or not at all due to asthma / allergy symptoms. I mixed Under the Weather with a creamy treat and crushed allergy meds. He ate all of it. Each day I noticed his appetite increased and he started eating and gaining the weight back that he had lost. I offered Under the Weather once a day in the morning for about 5 days. I will always keep this on hand and continue using it. Life Saver!!!!

Doesn't take much.

Using for sick kitten, does not take much. Have to roll into pellets then cornstarch to make un-sticky.
