Or, say a cat's roughly a sphere of radius 10cm, capacitance of an isolated sphere is C=4(pi)(epsilon_0)(radius) = radius/k_e = .1/(9x10^9) = 11 pF Ballpark.

  huh. I ctrl-f'd for "sphere" and missed it. There goes the high point of my saturday night. Maybe later they'll ask how many cats running in circles you need to levitate a dog wearing a ferrous vest.
