The inability for someone to see past the first step in a plan, thereby being clueless as to what to do when it is successful. So named because indoor cats always
pine to go outside, staring out the
window all day, trying to sneak out the
door, but once outside, they have no step 2 to the plan.
This
one guy was planning to kill his wife for insurance
money, but once he did, he had no idea what to do next and was caught quickly. He really had Indoor cat syndrome on that
one.
