Zylkene Capsules are a supplement designed to help cats and dogs manage stressful situations. Zylkene contains a natural product derived from casein, a protein in milk, that is well known to promote the relaxation of newborns after breastfeeding. Zylkene is palatable and easy to give: simply mix with food or give the whole capsule. It can be given daily and is both preservative and lactose free.



  • Zylkene Capsules contain a palatable, water soluble powder that appeals to both dogs and cats
  • Zylkene Capsules can be given whole or can be opened and the powder mixed with food, treat or liquids


Since its launch Zylkene has become a familiar product for veterinarians, behaviourists and pet owners world wide. It helps pets cope when facing unusual and unpredictable situations and can be used before occasions such as a change in their normal environment.

When to use Zylkene:
Zylkene can help support dogs and cats in situations where they find they need to adapt their behaviour to cope. These can include kennel and cattery stays, moving house, the arrival of a new pet or baby, sudden noises such as fireworks, travel or festivities. Many cats do not cope well in a multi-cat household, so Zylkene can help with the introduction of a new cat.
