## 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.
