Five stars

by Peter Morris -

A fantastic natural calming supplement. I use them for my cat during firework season and she is much less distressed

Works well

by Laura Wilson -

My dog is much calmer around new people since starting on these supplements. I noticed a change after about a week

Great calming aid

by Daniel Smith -

I use these for my cat before we travel and they make a huge difference to her stress levels. I always keep a pack on hand

Subtle but effective

by Thomas Evans -

It doesn't sedate my dog but just takes the edge off her stress. Great for general anxiety and adapting to new situations

A bit pricey

by Chloe Green -

It's quite expensive for only 20 capsules but the quality is high and they genuinely work for my cat's anxiety

Easy to administer

by Emily Moore -

I just sprinkle the powder over her food and my cat eats it without any fuss. No nasty side effects either. Highly recommend

Vet suggested these

by Robert Hall -

My veterinarian recommended Zylkene for my small, highly anxious dog. It has definitely reduced his fear responses. Excellent product

Good for thunder phobia

by Sophie Adams -

My cat panics during storms but these capsules make her much calmer and more able to cope. I start them a few days before bad weather

Great for vet visits

by William Carter -

I give these to my small dog before car journeys and vet appointments and it really takes the edge off his anxiety. Easy to mix in food

Really helped my nervous cat

by Jennifer White -

My cat gets very stressed by visitors and these capsules have made a noticeable difference to her anxiety levels. Very pleased

Excellent company to order from

by Kate Kennett -

My initial delivery package included some tins of cat food and a heavy bag of cat litter. The litter crushed the box of Zylkene in transit. I contacted Pet Shop and they immediately replaced the box and posted it out. Very impressed with their customer service.

Excellent product at value for money price

by Linda -

Zylkene is excellent for keeping my cat happy and calm at potentially stressful times. Vetshop gives a good service at a really good value for money price. I didn't opt for delivery this time as it took so long to arrive the first time, so I picked my order up. The process was smooth once I'd found the right door to enter

Good price and excellent service

by SimonW -

It was easy to order and arrived promptly. Certainly a lot cheaper than buying from the vets. The cat will only eat the powder inside if it's smothered in cat soup though!

Calming effect

by Naz -

This is perfect for cats that are travelling on aircraft. It just calms them down for the flight.
