It was either Aristotle or Soupy Sales who was asked, “If not interfered with, how high will a cat climb?” They didn’t know; but the answer is obviously, “As high as he possibly can.”
Anyone who’s ever had kittens and curtains knows the truth of this.
Yes, I’ve had more than one curtain ruined by these climbing cats. When confronted.. they just give you an innocent look and say are you talking to me?
