This product always helps my car when she is stressy and over groomes




Great product works good on the pet


Brilliant for my stressed out cat. We were prescribed this at our vets, but it is much cheaper to buy them online. Trusted supplier and wonderful service. Thanks


Zylkene has proved an excellent remedy when experiencing hositility between our female cats.


We've been giving Zylkene to our nervous Jack Russell for years now and use it with an Adaptil collar and it does appear to help him.
