Pod Cats.
Picture from Adventures in Catnip.
It appears that the Cats are using the same the same technique as the podpeople did in “Invasion of The Body Snatchers”.
This new development means Cats are well on their way to take over the world.
The only known means of incapacitating these “Pod Cats” is to scratch their chins. The tortured sounds they make that sound like, “Purr” will tell you if they are incapacitated.
