Awww... stories like this are so awful. And people wonder why it's so easy to become bitter about the human race. I think these two girls are detestable and I'm sure they're not done showing us what they're capable of.
I don't know... the kitten sure looks like he's happy to be alive and healthy in the pictures, hopefully he'll live the rest of his life loved. I don't fault them for saving it. I'd have wanted to. If he was really in a lot of pain, I likewise would not faulted them for putting him down. After all, we put down perfectly healthy but unwanted animals every day in most of our towns all over America. How many of those could we save if we let them tug at our heartstrings like this little fella did?
It's a precious kitten now, and ironically, a much luckier kitten than some.
You make a good point about all the other worthy animals that are put down each day. But saving this one sends a message I think about this sort of hideous abuse. Also, it will probably turn out to be the most loving animal if sent to a good home.
