I am sorry to read about the problems you are having with Ally and Connor. Over the past year I have taken in a number of foster cats (from military personnel). The first time this happened Emily definitely was NOT impressed with me (and let me know it). It took us about 4 months to reach a compromise in the house that everyone could live with. I made sure that all the cats had their "special" place where they could go and no other cats would bother them. I also provided lots of loving (and kitty treats). But everyonce in awhile she would still bat at them (even though she was half their size). I figured that as long as no blood and limited amounts of fur where on the floor (and they could tolerate each other), I was doing okay.

But the most important part was just time, time and more time...
