From the link:

Just as a human hand has five fingers, a panther’s front foot has five toes, but only four register in its track impression: the toe corresponding to the human thumb does not register. Look for four teardrop-shaped toe prints, asymmetrically arranged just like the four fingers on your hand: a leading toe corresponding to your middle finger; and a little toe, which, like your little finger, is physically smaller than the other three digits, and is on the outside of the paw...

[Salamander]

The "fifth toe" is *actually* the dew claw which is up on the animal's pastern and would not show when "charging", especially to their ludicrous degree.

Even though this is cartoonish, it is more anatomically correct.
