I can't tell even after downloading the photo, looking at it one way it looks like dog but my first impression of the head is cat. I can't tell what the size is as mentioned because i have no idea how tall the grass is or anything else to use to size it up. I've seen yearling cats that were only 40 or 50lbs as well as 20lb cubs and 200+lb toms. I'm no expert but I have seen about two dozen cats in the wild and the head shape fits, unless it's looking directly at the camera. What I'm seeing is it's looking past the camera to the right. I also can't tell about the tail being too fuzzy because the whole pic is fuzzy but then again it could be my eyes.
