Gary, you didn't have any choice in the matter. I believe that things happen for a reason and now that Pouncette, Gemmy & Karina2 have found a new home, I wouldn't say a nicer one, because I think you have made a wonderful home for all of them, but maybe since you will now have a space to fill, there is another that is in need and you will be able to help him or her. It is probably best that they not be around so many other cats, especially if Pouncette is aggressive and of course she will be very protective of her babies and it would cause her and the others stress. When one door closes another opens, so let's see what is waiting for you behind the next door. My heart goes out to you as I know you will miss them, but you were there for them and you will always remember and love them.
