Freedom - I could see clearly that the cat stopped, dropped what ever it had, then walked around a little bit towards the fence, then picked it back up and walked back in front of my house. No marks in the snow helped me figure out what it was.
I first thought about a kitten also, but figured that the cat would not be dragging their kitten in the snow.

catmandu- There are tons of little critters around my house for cats to catch for dinner.

Abby&Buddy'sMom- I followed the tracks as far as I could and I never saw blood. (I was first looking for blood thinking it was a hurt kitty)

Thank you all for your input, I'm sure it's nothing to loose sleep over, it's just one of those things that bother you and will keep bothering you till you figure it out!
