What was killed in my backyard today?

This morning I go to let me dog out and I see a hawk taking off from the ground beside my house. I thought this was strange so I went out to see what is was doing a sure enough there was a corpse - or parts of one anyway.

I picked up a tail that was about 6 inches long and had no fur and some intestines before I thought to take pictures to get this creature identified.

I’m the pictures you can see fur, bones, and what appear to be teeth. What is it?
