What is Zylkène?
Zylkène is a natural product, derived from casein, the protein in milk.
Since its launch in April 2008, Zylkène has been used in many common situations which our pets find difficult. Vets, behaviourists, nurses and pet owners have all found Zylkène to be a valuable support for helping pets cope with difficult situations.
