Is there anyway you can bring Kissy and Ginger inside to live??? At least that would take care of both of them and keep them out of Dilly's way. You've got a real tough decision to make. I wish I had some better advice, but I don't. Maybe Jenluckenbach, QSA or someone else in rescue has some ideas.

Good luck. Just remember, whatever you decide will be in the BEST interest of all involved.
