Zylkene Capsules Retail Pack are a great natural product that helps to control stress in cats and dogs, or help your pet deal with changing situations.

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.

Zylkene can help in the following situations:

  • Changes in environment
  • Being left alone
  • New person, baby or pet being introduced
  • Travelling
  • Kennel or cattery visits
  • Fireworks
  • Loud noises and thunderstorms
  • Vet visits
  • Celebrations
  • Moving house
  • Lactation
  • Weaning

Zylkène offers a cost effective and easy to give solution for stress in your cat and dog. It should be given once, daily and is hypoallergenic, preservative free and free from lactose. Zylkène has not been associated with any side effects, including sedation or memory loss and is suitable for many pets

Used on an older Lab who is slightly anxious when there is lots going on around her. Just takes the edge off.

It is always useful to have Zylken in the cupboard for the sometimes nervous boarding cat.

One of our rescue dogs suffers from fear aggression so is on these. We dread to think what she would be like without them. Firework season is not a good time for us since her reactions affect the other dogs.
