I tried putting Tommy in the bedroom, but then Scat sits outside the door crying to get in, and Tommy's on the other side of the door trying to get out. I kind of feel like it's going backwards at this point to keep Tommy in a seperate space. If anything, it seems that Ella is the one who wants to be alone. When Scat goes near her, she growls, makes those weird "pig" sounds, and then hides under the bed.
Ok, so Tommy came home with you on Saturday and all 3 have been hanging out together since then. Ella and Scat were happy before Tommy arrived. Since Tommy's arrival, Scat has somewhat accepted Tommy, but Ella has not. Now Ella is not only hissing at newcomer Tommy, she is also hissing at her old friend Scat.
Here's what I would do in your situation. I'd isolate Tommy. It may sound backward, but you want to restore peace to your household before you try again with introducing Tommy. To your cats (at least Ella), Tommy is an intruder who has rudely disrupted her happy household and the schedule she was used to. Once Tommy is isolated, I'd give both Ella and Scat a cat wipe bath (or maybe try the vanilla extract trick: http://www.thecatsite.com/Tabbytudes...-May-2003.html
) so they smell alike. My guess is that Ella is hissing at Scat because Scat smells like the intruder. See if that helps the situation. Make it a regularly ol' scheduled day (like it was before Tommy came). Have Ella and Scat eat together, play together etc. Hopefully, mother and daughter will get back to normal fairly quickly (hopefully before you leave on Saturday night!)
I would then start over with the introduction process and do a slow introduction (once you get back). If all goes well in the next few days before you leave (Ella and Scat are harmonious again), then take Tommy with you over the weekend (you might have to keep him separated from his mom and brother because they might not recognize him) and when you come back, immediately isolate him to another room (bathroom/bedroom) and go the slow introduction route. It sounds like Ella is the alpha (is she?). If so, focus on introducing Ella to Tommy and go at Ella's pace. I have read that with multiple cat households, once the alpha has accepted the newcomer, usually the rest of cats will fall in line.
If Ella and Scat are still fighting with each other before you leave, you may need to isolate them from each other for the weekend or bring Scat with you too. Then work on reintroducing Ella and Scat when you get back.
I'd definitely try to get Ella and Scat back to the way they were pre-Tommy first before making your next step.
Best of luck!
