I own a luxury cattery in Nottingham. I have used Pet Remedy plug ins, sprays and atomisers for some time now. I have had some brilliant successes with it and much prefer it to Feliway. I always use it for all my new guests and for some of my more timid regular ones too. 6 individual guests in particular have become different cats since using it, they are certainly much more relaxed and stress free and their owners have noticed a difference when they go home too. Thank you for developing such a brilliant product and helping many animals to become less stressed and have a better experience when coming to a cattery.
