Each refill provides 30 days of continuous calming pheromones, covering up to 400 sq ft, and pairs with a reusable diffuser designed for up to 12 months of use.

## 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: Great product. Keeps angry cats civil. - I bought these because my cats tend to fight a lot, especially at night. And the dog annoys them a lot too. I was recommended them by my neighbor. I can tell a major difference. My fat black cat (who is not fond of me) benefits the most. She is now a sweet cute girl who is very social with me. She likes to cuddle on my lap now. My anxious little grey tabby is far less anxious and doesn’t run when you cat call her. She now meows and perks up her butt ready for some scratchies. The dog doesn’t chase the cats as much either, and I’ve noticed the tabby actually rubs her head on the dog now, but the fat black cat still isn’t a fan of the dog. I can tell when the dispenser is beginning to be ineffective cus the cats will start arguing more. Each bottle at that time will have a bit in the bottom left too. I like to open the old bottle and new bottle with a butter knife (gently), use a dedicated old small plastic syringe from gas drops for my infant, suck out the remaining liquid out and add it to the new bottle. Might sound silly and petty, but it makes the new bottle last about a weekish longer than just throwing the old one away. Don’t spill it though because it’s oily and it a pain to completely clean up (personal experience). There isn’t any discernible scent that the human nose can detect. But it does work, I have witnessed my cats become much more chill. The coverage is good too. My house is just over 3000sqft and I put 3 plugs in commonly travelled areas or rooms the cats spend more time. One in a main hallway, one in my bedroom, and one in the living room. The pheromones spread enough that every area gets enough. Normal back and forth traffic across the house will carry the pheromones around, so I’d suggest only putting one in large areas or in rooms the cats spend most of their time. You don’t need one for every room, just higher traffic locations.
Review: Works for our household! - We started buying these a few years ago when our 2 indoor cats (siblings from the same litter) were having some territorial issues due the outside stray cats that would approach our house. They started fighting a lot and it was scary. So we started the plug ins and I used to have them all around the house. Luckily our vet said 1 on each floor should do it. We can tell when they're empty and need a new one when the cats start to get a little short tempered with each other. I replaced the upstairs one tonight and they both started happily sniffing the air! We love keeping our kitties calm and happy!

## 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.

### ⭐⭐⭐⭐ Effective Calming for My Cat, But Leaves an Oil Streak on the Wall
*by T***C on March 30, 2025*

I’ve been using the Comfort Zone Multi-Cat Calming Diffuser Refills for years, and they’ve consistently helped keep my cat’s behavior calmer and more balanced. Whenever a cartridge runs out, I can immediately tell a difference—there’s more agitation or restlessness. Once I replace the refill, the calming effect is noticeable again. For the price and the number of refills included, this is a great value, and it truly works as intended. However, I’m giving it 4 out of 5 stars because of a persistent design flaw. The diffuser releases the calming mist upward, and over time it leaves a streak of oil on the wall above the outlet. I find myself having to periodically clean the wall, which is inconvenient and could potentially cause long-term discoloration. I really wish they had designed it to diffuse outward instead of upward, which would likely solve this issue. That said, I’ll continue to use the product because of its effectiveness, but I do hope the manufacturer considers improving the diffuser design in the future.
