## 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

### ⭐⭐⭐⭐⭐ Good product.

### ⭐⭐⭐⭐⭐ My cats love it!

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.

### ⭐⭐⭐⭐⭐ Worth trying!
*by S***H on November 17, 2025*

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.
