📝 Product Details

If your cats are biting, growling, hissing, spitting, fighting, chasing, blocking access, stalking, staring non-playfully, scratching, or peeing outside the litter box, urine marking or spraying, the Comfort Zone Multi-Cat Calming Diffuser is designed to help address the tension that commonly occurs in multi-cat homes. Sharing territory, resources, or routine changes can create ongoing stress between cats, which often shows up as disruptive behavior, creating ongoing needs for cat stress relief.
This plug-in cat calming pheromone diffuser works as a pheromone diffuser to calm cats by releasing a continuous, fragrance-free and drug-free mist that mimics natural feline pheromones. Cats instinctively recognize these calming pheromones for cats as familiar and reassuring. When cats feel more secure, interactions may become calmer and more predictable. With consistent use, this cat diffuser calming multicat option helps reduce aggression for cats and supports cat stress relief. Many households notice calmer behavior within about one week. Designed for everyday convenience, the Comfort Zone Multi-Cat Calming Diffuser provides 24/7 calming support for up to 30 days when used with Comfort Zone Multi-Cat Diffuser Refills. Each cat diffuser and refill is designed to cover one room, making it easy to target areas where your cat spends the most time. The diffuser operates quietly and features a small, low-profile design that blends discreetly into your home. The consumer-preferred diffuser design keeps the bottom outlet open for easy use in standard outlets. Easy to use and mess-free, Comfort Zone Multi-Cat Calming Diffusers are expert recommended and tested to meet electrical safety standards. For best results, plug the diffuser upright in an open area with four feet of clearance around the unit, and avoid placing it under shelves, behind furniture, or near vents or windows. Comfort Zone Multi-Cat Diffuser Refills are available in 1, 2, 3, and 6 packs.
