Zylkene is a complementary natural calming substance that can help your dog or cat to cope with a stressful situation. It contains a natural product, derived from casein, a protein in milk, and it is very effective for use in helping pets cope when facing unusual and unpredictable situations, or before occasions such as a change in their normal environment.

Zylkene only needs to be given once daily and there are no side effects. It comes in a capsule that is very palatable and easy to give; simply mix with your pets usual food or give as a treat. You can even mix it with liquids such as milk, cream, gravy or the oil from a tin of tuna as it is water soluble.

Supports your pet in the following situations (for example):

  • Kennel or cattery stays
  • House move
  • Arrival of a new pet or baby
  • Being at home alone
  • Sudden loud noises, such as fireworks or thunderstorms
  • Travel
  • Vet or groomer visits.



Zylkene has a calming influence that will not sedate your pet and it is also hypoallergenic, preservative-free and lactose-free.

Suitable for cats or dogs up to 10kg in weight.

Fantastic product Emma on 2 May 2023

Zylkene was recommended for my cat due to extreme anxiety from attacks from a neighbouring cat. I put this over my cats food and she ate it no bother. Further it has made a real difference to her and her behaviour has improved greatly. I would thoroughly recommend.

A vet recommended this for our cat Guiness who has a habit of over-grooming his belly fur, leading to a bald patch, the idea being Zylkene may calm him and reduce this behaviour. Guiness loves this supplement mixed with his food and eats it all up. Although it has not solved the problem entirely, I have noticed a decrease in his grooming habit and some re-growth of fur.

Not for us freya-p on 22 March 2019

Unfortunately not for my cat. He has anxiety and picks out his fur, tried pet remedy plug ins, all feliway products and nothing worked. Gave this a try and mixed it in his food, Didn't touch it. Mixed in with treats and the squeezy treats still would not touch! I can't say if the tablet was effective as he wouldn't take it. Maybe should offer a trial/sample. Like a few tablets instead of whole pack.

Not effective Kitty on 6 September 2016

Very disappointed...don't feel the Zylkene has been at all effective.
