Bobcats, yes! However cats usually don't walk with their nails out. Alligators? Unlikely, but since they found one in Kansas( a neighboring state), you never know! A little far from the water for an Alligator though... Our stream is down the hill about 700 yards, or so...

Yeah that is true about the bobcats. Do you have large snapping turtles there? I am just guessing at this point! :)
