Pet Relax works by providing a highly attractive environmental scent that pets like cats and dogs respond to. In times of stress or anxiety our pets can get over stimulated, which leads on to the many different signs of stress we see in them. Having a calm dog or calm cat is helpful for all the family. The special Pet Relax blend of essential oils is valerian based and works by distracting pets from environmental stress. Cats, dogs, rabbits, small mammals and other pets have highly developed olfactory systems and are particularly capable of detecting volatile scents. The living environment of pets largely determines their quality of life and the importance of environmental scents is recognized as a key factor in helping anxious or stressed pets feel happier and more relaxed. When pets feel calm, their quality of life improves. Always consult your vet if your pet shows signs of stress or you observe any behavioural changes.
