And then there were two

As documented previously, Charlie has made himself at home here. Daily, the girls peer out the front windows and talk to Charlie. The other day, they kept referring to "two Charlies".

Interesting, huh?

Do you notice anything unusual in the below pics?




Any guesses as to how much trouble I am in with Skip over this second cat? He had been successfully ignoring the first Charlie, but two Charlies are harder to overlook.
