Kit the cat kept laughing at Bog the dog because Bog kept trying to laugh too but nothing came out but a bark.
Kit really wasn’t laughing as far as any humans knew, but Kit didn’t speak Bog’s language so thought that laughing sounded like meow and kept meowing wildly thinking it was laughing coming out and that sooner or later Bog would get the clue that chiming in meowing was in order.
Whatever was still funny Bog didn’t know but kept on trying to ask Kit what they were trying so hard to laugh at since Kit’s belly was heaving in and out leading Bog to believe that Kit was still trying to laugh.
It started out with Bill the bird getting out of his cage and Kit and Bog thought Bill was quite the star for getting free and started laughing out of nervousness that Bill would get found out and put back in his cage.
But then Kit couldn’t quit because once laughing gets started it’s something that goes on and on until enough yelling from a human puts the kibosh on it.
“Bark”, “Meow” went on and on until Kit and Bog were starting to strain their voices and then Morris the horse came whinnying into the conversation.
Bill was shrilling, Morris was whinnying and Kit and Bog were, by that time, getting laryngitis — so laughing stopped being funny and everybody settled down.
Kit curled up and started purring.
Bog tossed the ball off the wall while ignoring Bill the bird sitting on the curtain rod and Morris returned to the barnyard stall.
No humans had to intervene and everyone had fun for just a little while.
