I am sure that everyone on PT will make every attempt to understand your situation and give you all the help they can.

I think you will find if you continue to read PT that anyone on this forum in your position, and a few of them have been, would have their cat euthanized in their arms rather than walk away from them outside or leave them in a very high-kill shelter knowing they had no hope of adoption. How did people get the impression that you would leave her outside if you couldn't find someone to adopt her? What are your plans for the other cats if you can't find homes for them? I ask because I'm confused by your posting since it sounds like you are trying to find homes for them as a sort of add-on. Forgive the questions, we are trying to get to know you.
