I’m a vet nurse and I adore Pet Remedy. I use it all the time at work and also for my cat at home. I prefer it to Feliway (although often both in combination work very well). I do feel it probably works better for cats than for dogs. Some cats react to it as if it were catnip (valerian can have that effect on cats) but most find it very calming. The only downside is that many humans don’t like the smell of valerian, although Pet Remedy have managed to reduce the strength of this smell so it isn’t as overpowering as it used to be. This pack is fantastic value for money and I’d highly recommend it to anyone starting out with Pet Remedy.
