by a cat.

Has a cut right above it's tail, other than that, seems to be fine, just scared.
I know even though it seems to be fine, it's probably going to die.

What do I do to save it???
It's pretty young.
But doesn't look like it's an infant.

What food should I give it?
I only have paper towels to give it for bedding for now...but that's probably not enough, should I give it a shirt or something to lay in?
