Trusted for over 20 years and tested to meet safety standards, this 6-pack value set supports a harmonious home by minimizing scratching, urine marking, and aggressive behaviors, making it the go-to choice for professional pet parents seeking peace of mind and a calmer cat environment. ## Description Comfort Zone Multi-Cat Diffuser Refills are designed to help reduce common signs of stress in homes with multiple cats, supporting calmer interactions and improved behavior. These refills pair with all Comfort Zone cat calming pheromone diffusers and are ideal for cats' everyday stressors like routine changes, new environments, and visitors. When cats share space or compete for territory, tension can lead to unwanted behaviors. A cat plug in pheromone diffuser must be used with this product. Each refill delivers 24/7 calming for up to 30 days, helping maintain a consistent calming environment. The fragrance-free, drug-free pheromone formula mimics a cat’s natural calming pheromones, which cats instinctively recognize as a signal that an area is safe, familiar, and secure. These refills help reduce behaviors commonly associated with cat stress, including urine marking, scratching, swatting, biting, fighting, growling, hissing, spitting, non-playful staring, stalking, chasing, and blocking, which are often seen in multi-cat households. Most cats begin to show improved behavior within as little as one week, with continued benefits through regular use.Each diffuser and refill is designed to cover one room, making it easy to target areas where your cats spend the most time. Easy to use and mess-free, Comfort Zone Multi-Cat Diffuser Refills are expert recommended and tested to meet electrical safety standards, offering peace of mind for everyday use. 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. Replace refills monthly to help provide continuous calming support and promote a more comfortable, stress-free home for your cats. ## Features - REDUCE & REUSE: Compatible with Comfort Zone diffusers only; Comfort Zone diffusers are reusable for up to 12 months; just replace the refill monthly for a continuous calming effect - TRUSTED & EXPERT RECOMMENDED: Comfort Zone has provided care with cat calming pheromones for over 20 years, making it a trusted choice for pet parents - MULTI-CAT CONFLICT: Use to help reduce multiple cat household tension and aggressive behaviors like swatting, scratching, biting, fighting, hissing, growling, spitting, screaming, non-playful staring, stalking, chasing, and blocking - DRUG & FRAGRANCE FREE: Drug-free solution so you can feel good about helping your cat feel good - SUBSCRIBE & SAVE FOR 24/7 CALM: Get Comfort Zone delivered on your schedule to help maintain continuous calming support; Save money automatically and skip reordering, to spend time where it matters with your cat; - SAVE WITH VALUE PACK: This value pack includes 6 refills, providing up to 6 months of continuous calming support; Use with a Comfort Zone Diffuser to get up to 400 square feet of coverage for 30 days - SAFE & TESTED: Meets Intertek electrical safety and certified to UL standards ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 10,616 Reviews | ## Images ![COMFORT ZONE Multi Cat Calming Diffuser Refill, 6 Pack – Cat Calming Pheromone Refills Help Reduce Anxiety, Stress, Scratching, Urine Marking, Multi-Cat Aggression, (30-Day Refills, 180-Day Supply) - Image 1](https://m.media-amazon.com/images/I/81OKu8CEbcL.jpg) ![COMFORT ZONE Multi Cat Calming Diffuser Refill, 6 Pack – Cat Calming Pheromone Refills Help Reduce Anxiety, Stress, Scratching, Urine Marking, Multi-Cat Aggression, (30-Day Refills, 180-Day Supply) - Image 2](https://m.media-amazon.com/images/I/81uRaT4hM3L.jpg) ![COMFORT ZONE Multi Cat Calming Diffuser Refill, 6 Pack – Cat Calming Pheromone Refills Help Reduce Anxiety, Stress, Scratching, Urine Marking, Multi-Cat Aggression, (30-Day Refills, 180-Day Supply) - Image 3](https://m.media-amazon.com/images/I/71Cpm07XcgL.jpg) ![COMFORT ZONE Multi Cat Calming Diffuser Refill, 6 Pack – Cat Calming Pheromone Refills Help Reduce Anxiety, Stress, Scratching, Urine Marking, Multi-Cat Aggression, (30-Day Refills, 180-Day Supply) - Image 4](https://m.media-amazon.com/images/I/71gIWAbHP0L.jpg) ![COMFORT ZONE Multi Cat Calming Diffuser Refill, 6 Pack – Cat Calming Pheromone Refills Help Reduce Anxiety, Stress, Scratching, Urine Marking, Multi-Cat Aggression, (30-Day Refills, 180-Day Supply) - Image 5](https://m.media-amazon.com/images/I/91I1jSYgwJL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Do comfortzone refill fit in the feliway difusers?** A: 90% Sure yes. I've been using Comfort Zone & Feliway interchangeably, just what I can get ahold of, and haven't had a diffuser fit problem. **Q: Does the 2x refill work with the original diffuser, I see the outer casing is different, is that needed for the 2x to be effective?** A: Yes, they are backward compatible. **Q: Do all contain a diffuser?** A: No, there is no diffuser in this pack. You will see a picture of the diffuser on the front of the package of those that contain a diffuser(s). **Q: How well does it work for indoor cats marking because outdoor strays are driving them crazy?** A: I've not used these specifically in that situation, though I know exactly how aggravating that is! I've introduced several rescued feral cats into my main group of indoor cats in years past, and only wish I would have had this product back then. I can't say it will fix the problem you're having, but if it were me, I would sure TRY it. I'd saturate the home with the plug-in diffusers, then spray directly on whatever areas your cats are in when they see/hear the outdoor cats. I honestly think it would be worth a try. Right now I have an outdoor kitty who comes and lies up against the door here (I take care of her, feed her, and she has shelter and a heated bed!), but my indoor cats here just lie against the door on the INSIDE when they hear her. No meowing, no crying, no scratching. I'm in a small apartment and two plug-in diffusers seem to work wonders. I personally hope to never be without this product... even my petsitters always remark on how they "can't believe how well everyone in here gets along". Good luck. ## Frequently Bought Together - COMFORT ZONE 6 Pack MultiCat Diffuser Refills; Cat Calming Pheromones Help Anxiety; 30-day refills - Comfort Zone Savings Kit; 2 Multicat Diffusers & 2 Refills; Cat Calming Pheromone; Reduce Stress, Aggression, Fighting, Urine Marking, Scratching - Comfort Zone Cat Calming Collar Savings Pack: 2 30-Day Calming Collars for 60 Days of Calm; Cat Pheromones Help Anxiety, Reduce Stress, Urine Marking, Scratching; Indoor or Outdoor Cats; Long-Lasting --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/113963855-comfort-zone-multi-cat-calming-diffuser-refill-6-pack-cat](https://www.desertcart.pt/products/113963855-comfort-zone-multi-cat-calming-diffuser-refill-6-pack-cat) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-10*
