I brought a male kitten (Tommy) home Saturday to my 2 female cats. I live in a one-bedroom apt. so I really can't keep the cats separate. Ella (9 yrs old) is the alpha and also the mother of Scat (7 yrs old). Ella was scared of Tommy at first, and Scat hissed and swatted at him. Now Ella is growling at Scat, and they occasionally erupt into fighting with each other, growling, hissing, awful sounds (I didn't get any sleep last night!). I have paid a LOT of attention to Scat and Ella, and I've rubbed a cloth on each of the their cheeks and have gone back and forth. I haven't really put Tommy into the mix. It is so disheartening to see them fighting with each other. I don't know what to do. And they both are still hissing at Tommy. Help!
