Great deal, super effective
Fits great in the comfort zone diffusers, my cat hasn’t woke me up in the middle of the night, after two weeks of adjusting, my kitty is calm and comfy. Super affordable solution to the name brand. Great bang for your buck.

“Instant Calm and Amazing Results for My Cat!”
TopSum Cat Calming Diffuser Refills have been a total game-changer in my home. Within the first 24 hours, the atmosphere became noticeably calmer. My cat relaxed, stopped pacing, and settled into her cozy spots without any tension or restlessness. The scent is subtle and not overwhelming, and the refills last exactly as long as advertised.What I appreciate most is how quickly the difference shows—zero hassle, no mess, and consistent results. If your cat is anxious, adjusting to a new environment, or simply high-energy, this diffuser makes an immediate and meaningful impact. Highly recommended for any cat parent who wants a peaceful, stress-free home.

Definitely works!
This stuff really works. I have a little red furry demon that turns into a well behaved and positively loving kitty when these are plugged in. Honestly, I have run out twice (not paying attention) and the difference is remarkable. She really is a good kitty, but she is a little touchy. She’s much more relaxed and just plain happy with the pheromones. They don’t drug your cat or make them any different except for making them more calm and perhaps giving them a sense of being safe, as in they don’t have to feel defensive all the time. The price is decent for the quantity- well worth it. I believe that it lasts for the full 30 days, but can’t swear to that. I just replace it when it’s empty. There is no scent at all which is an extra bonus.

Great value
Pleasantly surprised with these as I normally use Feliway. Tames my four cats attitudes nicely.

Okay but not amazing.
Pros:-soooo much cheaper than Feliway-compatible with the Feliway diffuser plug-in-seem to work okay in terms of chilling my cat outCons:-I don’t think they work as well as the Feliway-they diffuse much much faster, so I go through them at about twice the rate of a FeliwayUltimately I think it’s worth it because it’s like 6 bottles for the price of 1 Feliway, but I do think it’s not as effective and the fact that I go through 2 per month is a little annoying.I’ll keep buying this brand probably because I’m not made of money, but I wouldn’t say it’s a totally solid dupe. It’s completely fine! But not amazing.

Great, Budget Friendly Alternative to the Big Brand
These seem to work as well as the name brands. You get 6 in this package. I like that it does not give you the extra wall plug-ins. It’s good to have quite a few of those plug-ins, periodically, because if you use one for too long it increases the likelihood it will catch on fire. But if you get too many of the extra plug-ins it just creates extra garbage landfill. This option to buy just the refills only, and at a reasonable price is perfect.My cats do stop to smell it. That makes me think it is working. The refills were all filled to the amount I’m used to, and arrived in good condition. It’s very easy to use as you just unscrew the top and then stick it into the plug-in and then plug it in the outlet. When the liquid is out then I replace it. I think each lasts about a month, but I need to have more than one in at a time.They leak a teeny bit sometimes, when you are holding them, but once in the wall they are fine.These are a definite win for me and my cats.

I feel this works well for my anxious cat. (5 stars) But the price fluctuates so much, or it’s unavailable for purchase. Loses a star -Good product, but inconsistent buying options.
Hanisa Rahbari –
It’s been two weeks that I started using this product and my cats fight right infront of the device. I’m still hopeful that some day it will show something.
Kath –
It works for my “agressive” cat that doesn’t like the company of other cats. It calms him a little bit. I’m only doing 3 stars because the price is insane. They increased it recently and now it’s very expensive… ridiculous.

One month review:In my opinion, buying this off-brand for a few dollars ($10-20) less than the original Feliway diffuser is not worth it. I’ve fostered dozens and dozens of young cats and kittens for local rescues, and have taken on several difficult permanent residents like the one I’m currently troubleshooting.Upon receipt, my initial concern was the lack of a Canadian (or USA… or any) electrical compliance mark, such as CSA, cUl, cETL, or equivalent. That’s mainly because I’ve worked in electrical compliance for imports of equipment (i.e. anything that plugs into the wall) into Canada and and am hyper aware of this issue. This is not ideal for anything that plugs into a wall socket, but common on this platform. I urge the manufacturer to seek at minimum a US certification. That being said, I’ve kept a close eye and have not experienced any electrical or overheating issues. This makes me feel like some kind of certification would not be difficult to obtain. The included pamphlet indicates at least a major US partnership, so I’m at a loss as to why this has been overlooked.Secondly, I’ve had lots of success with the original Feliway diffusers, but not so with this brand so far My veterinarian has recommended switching to the newer Feliway Optimum formulation which I’m looking into.I bought 2 of these diffusers and a 6 pack refills. Willing to connect if you’d like?

Not a good buy. They last only 2 weeks. Seems cheaper, you decide.
