Our cat loves catnip. We sprinkle some on the ground and he rolls around in it like a mad man. My son observed this strange behavior and decided to see if catnip had a similar effect on him.
He grabbed the container of catnip, opened it and sniffed.
Then he started rolling around on the ground just like the cat.
The cat stopped, stared at him, and ran off.
Needless to say, I'll be keeping the catnip away from my boy.
