Zylkene is a natural product which can help to support cats and dogs when in a stressful situation.

The capsules contain a natural product derived from casein, a protein in milk, which is well known to promote the relaxation of newborns after breastfeeding.

This treatment is ideal for situations such as the introduction of a new pet or baby, house moves, cattery or kennel stays and fireworks.

To administer, give directly by mouth or open the capsule and sprinkle onto your pet’s food, to improve compliance.

Please remember that there are many ways our pets can react to new situations and not all animals respond in the same way, so keep an eye on your pet and look out for any unpredicted behaviour changes.

Key Benefits of Zylkene:

Easy To Give
