Hello all, I am looking for advice on which brand to get. We have used the "Comfort Zone with Feliway" one before, and I am not sure if it helped, but let's say maybe a little bit. However, I went to buy refills and apparently they are just called "Comfort Zone" now. I don't think it contains Feliway anymore? I did a little reading online, and it appears that the studies are not consistent on Feliway helping, but Feliway appears to be the original product. But now there's a bunch of other brands too. And to complicate things further, there's also Feliway Original and Feliway Multicat. I am trying to use this as an adjunct to a Jackson Galaxy stepwise method of introducing of my 2 cats to the new kitten. (We are still at the stage where they eat on the opposite sites of a door. well, 2 of them do... one of my older cats won't eat next to it so she's eats few feet away. Sometimes she won't eat. This is why I am looking into this ) So I need some advice on which brand and what subtype to get. So many options, so little evidence. Any input is appreciated!
