ThunderEase Multicat Calming Pheromone Diffuser Refill | Powered by FELIWAY | Reduce Cat Conflict, Tension and Fighting (30 Day Supply)

I order these every month to keep my cats from fighting. They always arrive quickly. I started purchasing Feliway Multicat to reduce tension and fighting among cats after bringing home a newcomer. After 1 week using 1 diffuser, I noticed a big reduction in animosity and attacks among the cats, so I kept adding additional diffusers in highly used areas to enhance the atmospheric concentration of the synthetic hormone until I reached the optimal quantity when the cats got along, which was 5 diffusers for my 1300 sq ft space with high ceilings. Using 5 diffusers, there is no animosity at all and the cats are even starting to like each other. The cats alert me when the bottles run dry, as they start fighting again. I was bereft when Feliway stopped selling the 6 refill pack because the cost is so high for 1 or 2 refills at a time. Furtunately, Thundershirt started offering a similar product in 6 pack that fits the Feliway diffusers perfectly. I immediately noticed that Thundershirt brand worked slightly better than Feliway. Recently, Feliway started selling the 6 pack multicat version, so I ordered it again, but they changed the design of diffusers and refill bottles. While the new design bottles still work with old version diffusers, they leak solution something aweful, so I have not ordered any more since I will be using the old style diffusers for a long time.I don't know what I would do without this product.Before trying the hormone product, there was nothing more that could be done to get my cats to get along and I was considering that I find a different home for the newcomer cat, which I really did not want. This product really made a major difference in my cats behavior, and was the only thing that finally allowed my cats to share a happy household.Since most multi-cat users of this product do so for years (I am going on 2 years now), I really, really wish Thundershirt would offer this 6 pack on a reduced cost monyhly subscription basis.

I bought this product about 2 years ago and have been meaning to write a review on it but kept on forgetting. Today it popped up on my screen as to write a review so here I am.When I bought this product, I had two cats and one was always afraid and would run and hide the minute someone came into the house. He would stay hidden until it was nighttime. My other cat, even though I have a scratching post for him, would use the side of my couch as a scratcher. I tried all different calming sprays and even covered the couch. Nothing worked. I fixed the side of the couch with the same color and material and it was during that time that I bought this product. I noticed the difference in both cats within a day. The one that scratched my couch doesn’t do it anymore and the other cat (he passed away last October), he was still a little afraid but he wasn’t running to go hide…he would stay out on his cat bed or go a lay on the other cat bed with my other cat.I definitely recommend this product!

I had reservations about this, since I had tried another product without success. Background: Kitty Tess and her 2 daughters began to have problems when Tess had an abscess on her face, probably an accidental bite while playing with the kitties. When she came home from the vet and stepped out of the cat carrier, the first thing she saw was Sophie, one of her daughters. Tess immediately attacked Sophie, and from then on these two have been adversaries. So sad, because previously they were best friends. Anyway, since then Tess and Sophie have been total enemies. Sophie has turned into a bit of a bully, and walks into a room and challenges Tess with a stare. Tess growls, then the fight starts! (Zora, the other daughter, just stays out of all of this. She is a total pacifist!)I tried another product (Sentry 484243Sentry Calming Diffuser for Cats, 1.5-Ounce) but didn't notice any change. I did like this product for the nice lavendar scent for myself, but it did nothing for the aggression. Then I tried CEVA Animal Health FELIWAY MultiCat Starter Kit for Cats (Diffuser and 48 ml vial. No difference in behavior noted. However, I did see that the stem that went up into the diffuser was scorched. That led me to looking at the reviews for this, and I saw that many of these diffusers had not only overheated, but actually flamed!So I ordered this product, Thunderease, due to the reviews, but since the diffuser appeared in the pics to be the same as the one that overheated,I ordered another Sentry Calming Diffuser. Why? Because I didn't want my house to go up in flames! I am using the Thunderease in the Sentry diffuser, since this one hasn't had any problems with overheating. (I removed one star for the potentially dangerous diffuser.)So, here are the the results. I have seen all the kitties being "chill". Sophie and Zora (Zora is the pacifist) have been playing together, something I haven't seen in months. Also, Sophie has been much less challenging, and has been asking to play with both Zora and *gasp* Tess! So far Tess hasn't actually played, but there is much less growling and slapping. I hope that eventually they all will get along like they used to to. This product has given me hope.Update - Happy House! 3 weeks of use, and all are very nice to each other. The two combatants have even touched noses and not parted with slapping and hissing! They all nap close to each other, and don't seem as jealous of my attention as they were before. Great produce!I just wish that the potential problem with the diffuser would be solved, then an easy 5 stars.
