How does it work?


Zylkene contains a natural milk protein called casein that has been clinically proven to promote the relaxation of new-borns after breastfeeding. Casein delivers ‘calming messages’ to the brain via the body’s natural ‘messenger’ system (scientifically known as Neurotransmitters) helping calm a new-born.  Zylkene uses this same protein to naturally help calm your cat or dog.

Easy to give.


The complementary feed is easy to give. For cats or small dogs, split the capsule and mix the powder into their food.  



When to give Zylkene?


Give Zylkene 1-2 days before a predicted stressful event or change in environment.  These short-term triggers may include firework displays, thunderstorms, being home alone, travel or boarding, moving to a new house, a trip to the groomer or vet.

Zylkene calming supplements are an ideal choice to help support your cat or dog in challenging situations.
