Your quandary reminded me of the Serenity Prayer that someone once gave me when I needed it so now I pass it to you:

God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.


You already had the courage to change things for the better for these cats even though they weren't yours. I suspect, that although it may be difficult, you'll know the right thing to do when the time comes. If you can't change things, you won't. If you can change things, you will. Trust yourself.
