I just tried the 2nd introduction between my 2 cats and one I just rescued. Itook the rescue tish put her from her safe room to another room then I took Bella and Chloe and put them in the safe room to smell and so I could let tish explore well Bella my alpha just started growling and hissing really bad at Chloe and me pretty much so I didn't even try to let them all in the same room. I don't know what to do I don't want my kitties hurting each other PLEASE HELP GUYS PLEASE
