Feliway Spray 219mL is a synthetic copy of the feline facial pheromone, used by cats to mark their territory as safe and secure. By mimicking the cat's natural facial pheromones, Feliway creates a state of familiarity and security in the cat's local environment. As a result, Feliway can be used to help comfort and reassure cats, while they cope with a challenging situation and/or help prevent or reduce the stress. Both male and female cats, because of hormonal and behavior problems, can start spraying urine on objects or areas. Feliway contains pheromone-like substances which discourages this behavior when it is applied to the area the pet has sprayed. This spray canister comes with 219 mL of fluid- but 20 mL and 75 mL canisters are also available. You'll love the way this spray really works to calm your cat, so order it today!
