Bama was standing on my legs while I was reading posts when all of the sudden he dug down with his toenails and nearly poked holes in me!   He saw a cat in our neighbor's yard, and oh my goodness, he couldn't let it be!  I trimmed his nails a couple of weeks ago, and they really don't need it again--yet--but man, those things HURT!   He's standing on his stool looking out the window now, just watching for the cat to come back into view.
