Zylkene is a calming supplement that contains a natural ingredient derived from a protein in milk called casein that has clinically proven calming properties to help relax cats and dogs. It is a peptide (protein) molecule, well known to promote the relaxation of newborns after breastfeeding by delivering 'calming messages' to the brain via the body's natural 'messenger' system (scientifically known as Neurotransmitters).
Zylkene capsules are a tasteless powder which can be given in multiple ways; it can be mixed in with food or dissolved with water – great for fussy eaters.
