## Description

Vetoquinol Zylkene Calming Support Supplement for Small Dogs and Cats, Helps Promote Relaxation and Reduce External Stress Factors, Daily Behavioral Support and Anxiety Relief for Dogs and Cats, 75mg

Review: It works but I wanted something where my cat could just enjoy chilling out with family, I know cats sleep a lot anyway but this really knocks him out where I don’t get enough time with him. I hope that eventually he will relax in his new home and I can enjoy quality time with him.
Review: I've been pretty happy with Zylkene! I ordered it for two of my anxious senior dogs. It did not work for one of them, but his issues seem to run deeper and he's required something a bit stronger from the vet. For my chihuahua, though, she would tumble every time we ran the dryer before we started her on Zylkene. Since it's a capsule, I just open it and sprinkle it on her food each morning, and it takes the edge off enough that she no longer has issues when we run the dryer.

## Questions & Answers

**Q: Does it have a smell?**
A: Well, I just went and sniffed it for you. 😊 The capsules don’t, and I open them and pour the powder onto my cat’s wet food every morning. I’ve never noticed any smell. 

It’s made a difference for her. Been buying them at least a couple of years now.

**Q: Can can zylkene be safely given along with bach rescue remedy for pets?**
A: I don’t know the answer to your question. My vet recommended this for my pet so I would recommend you ask your veterinarian the question...

**Q: Are the capsules compostable?**
A: These capsules seem to be made of the same geletin based material as capsules for human supplements/medications. They melt away so I would say yes, they're compostable.

**Q: Can this be mixed with a bit of water and put into a syringe for oral administration?**
A: Probably.  I open the capsule, put it on my cat's wet food and add a bit of water.

I have always used this product over the years for my dogs who have anxiety after a death of another dog. I recently used for 16 yr old dog so he would be relaxed on plane
