Review: Worth trying! - I do feel like this helped my cat who was having a flare up of sorts. He was sneezing, watery eyes, hot ears. We mixed this with some churu food and it perked him up within 24 hours. My other cat wouldn’t eat it so we did the trick where you put some on his paw and he has to lick it off and he ate it just fine and it helped his symptoms too. Definitely recommend.
Review: Great great product for Upper Respiratory Infection - I ordered this late in the evening last night and received it late morning, thanks desertcart prime. My 17 year old cat got an upper respiratory infection. It started out as just sneezing but last night stopped eating and drinking watering eyes. Vet was closed so I read all the reviews for other supplements offered. This was the most expensive but bigger in size for gels or paste. Booboo does not eat wet food or treats so I needed this kind. Gave it to him as soon as I received it. Pump worked perfect and I put it just under his nose. He licked it up right away. I thought the smell was bad, but I wasn't eating it. Second pump put in his mouth no problem. Well by 4 pm today he got up and ate/drank and was not sneezing constantly. Gave him his night doses at 8:30pm. He only sneezed twice, no tearing and is out off my bed and cuddling by me. Will keep giving him a the week to make sure he is totally ok. This saved me a trip to emergency vet and from other reviews is cheaper here than from the vets office who recommended this to others. Great product and thank you for getting my geriatric kitty back to health in one day. Sorry for the length but wanted people to know how great this worked for Booboo as URI is serious when they stop eating and drinking and they r so stuffed up. All clear now yeah. Update:. I gave the paste to him for 5 days to make sure the URI was totally gone. He was asymptomatic after 3.5 days. Hasn't had a reoccurrence since and not one sneeze or eye watering either. Still have lots just in case.

## Questions & Answers

**Q: Is the bottle recyclable?**
A: I examined the container and there is no indication that it can be recycled. It does not have the "triangle" logo on the bottom of the container indicating it can be recycled.

**Q: is a syringe furnished with this product?**
A: No, the product is a thick jell. The pump mechanism works to deliver a small amount with each push. I put two 'pumps' on my fingers and both cats enjoy their treat. They lick my fingers clean.

**Q: Do i need to refrigerate?**
A: No refrigeration is required.

**Q: how many for price?**
A: No

### ⭐⭐⭐⭐⭐ My cats love it!
*by R***Y on February 12, 2026*

This product works well! My two cats enjoy the taste when I put it on their wet food. My cat deals with shedding and dandruff, but I feel her healthy routine combined with the Oral Paste is helping. The cats doing well certainly reduces all the vet appointments.
