Compatible exclusively with Comfort Zone diffusers, each refill lasts up to 30 days and covers 400 square feet, promoting a calmer environment. Trusted for over 20 years and certified for electrical safety, this 6-pack value set supports continuous, expert-recommended feline stress relief. ## 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. Review: Duraron menos de 10 días, no hicieron algún cambio en mis gatos - Fue un desperdicio de dinero, esperaba que duraran al menos 2 o 3 meses, puse 3 en simultaneo por toda la casa y no cambió en absoluto el estado de animo de mis gatos, por demás... ni siquiera llegaron a los 10 días. Simplemente fue dinero tirado a la basura... Review: Not a miracle cure, but definitely work - I have been using this product for a year now. We have a two story house and have one upstairs and one downstairs. You do not smell anything from it first off. I have three adult male cats and one very shy female. This is not a fix all and does not work some miracle with them. However we will continue to purchase this and keep them in the home. While it’s not a huge or drastic change we always do know when it’s out and time to replace it. My cats don’t pee in places they are not supposed to, so I am not sure how it changes that specific behavior. But our very shy girl is out and more active and adventurous when we have these. That is one big difference we see. The boys still tussle but it’s a very obvious play fight, it’s not always just play when these run out. The cat zoomies still happen but they are not as hardcore parcore as they are when we don’t have these plugged in. In short, yes they work, yes we see a difference in all 4 cats. But it’s a slight adjustment to their behavior and not something that makes them do a 180. None of the our cats seem bothered by them so I feel safe with this product when it comes to their scent sensitivity. They are super easy to use and just twist in and out. Hope this helps any other cat parents out there who want a fully honest review. And again we have had these in our home for over a year now. ## Features - REDUCE & REUSE: Compatible with Comfort Zone diffusers only.

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. ## Customer Reviews ### ⭐ Duraron menos de 10 días, no hicieron algún cambio en mis gatos *by C***N on 31 March 2020* Fue un desperdicio de dinero, esperaba que duraran al menos 2 o 3 meses, puse 3 en simultaneo por toda la casa y no cambió en absoluto el estado de animo de mis gatos, por demás... ni siquiera llegaron a los 10 días.

Oli is part Russian blue and part Schizophrenic. Sophie Grace is part Main Coon and Petrified Sweetheart. Sophie is still afraid of us after 5 years. It breaks my heart to think of what happened to her before her 8 weeks when we got her. Sophie has tolerated Oliver, but they are not best friends. Oli would like to be an only cat and he does his best to get rid of Sophie, (it’s not going to happen). He takes Sophie’s blanket from their room and hauls it to the laundry or to the trash in the kitchen, he eats her food and will push her out of the way if she is sitting in her favorite spot in the window. They got along reasonably well until Oli had to have some teeth pulled. He was so angry when he came home, he took it out on Sophie. I had to separate them for a few days, and I was in a panic mode trying to figure out what I could do to calm him down. The Vet told me to get a Pheromone product and that should help. On-line I found several products that were very insightful and after much review I chose Comfort Zone. This product is amazing, it calmed Oli down and he was no longer screaming every time he saw Sophie and it helped her nervous little body to calm down. At first, I purchased one Comfort Zone to give it a try and put it in my office. I noticed that both cats were in the same room and not fighting. I couldn’t wait to order 6 more. I have them upstairs and downstairs and two in their room and we are back to a calm house. Well, Oli would still like me to get rid of Sophie, he is still very jealous of her and resents me giving her attention, however, Oli is no longer dragging her blanket out of their room. I HIGHLY RECOMMEND COMFORT ZONE. It has saved our peaceful home from a constant battle. Now, both cats are sitting in the window together! I am sorry I didn’t find Comfort Zone 5 years ago This product is a game changer. ## 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.de/products/188222752-comfort-zone-multi-cat-calming-diffuser-refill-6-pack-30](https://www.desertcart.de/products/188222752-comfort-zone-multi-cat-calming-diffuser-refill-6-pack-30) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-30*
