Product details

Zylkene is a natural product that helps your dog or cat feel less stressed and return to their normal happy selves.

How it works

Zylkene contains a natural product derived from a protein found in milk and works to calm your pet when they are feeling stressed or worried. The ingredients soothe their brain receptors, helping them to feel less stressed.

The Zyklene powder is packed into capsules which can be fed whole. If your pet refuses to swallow pills you can still give them this treatment. Simply open up the capsule and mix the powder in with your pet's food – they won’t even notice it’s there! It is designed to be fed to your pet once a day with a meal or treat.

Since Zylkene is a natural product that has little to no known side effects, you can feed it to your pet for as long as they need it. It can be given for short-term stress, possibly related to changes such as a house move or unfamiliar visitors. Or if your pet is adjusting to a more permanent change of circumstances (like being left alone during the day) they can be given Zylkene for longer periods until they settle down.

Key benefits

  • created from a natural product found in milk protein
  • can be mixed with your pet's food for easy feeding
  • designed to be given once a day either short or long-term
  • few side effects.

When to use it 

Animals react to stress in different ways, so it's important to learn how to spot the signs of it in your pet. Is your cat withdrawn or does she run away and hide? Is your dog more grumpy or being naughty? In scary or unfamiliar situations, pets can show that they are feeling stressed through bad or unusual behaviour.

If the cause of stress is temporary (such as a new visitor in your home or loud building work taking place) your pet will often return to normal once the problem’s removed. However, permanent changes such as a change in their routine or a new pet in the house might need you to take further action to reassure your pet.

  • Works for us
    It’s not made my crazy cockers into super saints, nor did I expect it to,but it has calmed them down,and made my youngest less fearful and stressed about things that ‘may get him’ like traffic cones hiding in long grass, he is so weird bless him.

  • Sadly didn't work at all for my dog
    Bought for my elderly labradorX who gets very stressed when travelling. Persevered for a month to give it a fair trial but no effect whatsoever. Easy to use. Tried a number of other products but without success.

  • It’s working for us!
    My 14 year old neutered Tom, started spraying indoors recently. I aslo have 2 spayed females. As you can imagine, it’s been a nightmare! The vet said it could be anxiety and prescribed Zylkene and said it works for some cats. Well it’s worked for my boy, thank goodness and I’m now buying it online for convenience. Between Zylkene and a lot more cuddles and attention from me, my boy is now fine. Highly recommend!
