Dumped Cats, Again

I am so angry and frustrated. I went outside this a.m. and heard a funny sound,
looked around, and there are TWO kittens in the flowerbed. They are both gray.
One is longhaired. They look to be in good shape, except for fleas, ticks and
stickers, and are *very* well socialized.
Remember the closest house to me is 1/2 mile and I already know they didn't
come from there. Somebody deliberately brought them up the drive and dumped
them, probably last night.
I can't keep them. I can't really even take them to the shelter and expect them
to be adopted any time soon. They have 90 cats already and are about to cull
and take some to the city pound for euthanasia.
They're so cute. It's so sad.
