Continuity mistake: In the scene where Conrad and Sally are signing the contract, they have the pens in their hands, but when Cat says, "Give me five!" the pens have disappeared.

Continuity mistake: In the scene where the cat cuts off his tail, when he first hits it with the knife it bounces off but in the next shot it went through.

Continuity mistake: At the end of the movie when the Cat finished cleaning up the mess and was packing Thing 1 and Thing 2, everything looks immaculate except in one scene, in the corner of the living room, there are still purple splashes.

Continuity mistake: When Cat fills up the cupcake tray it is very messy with cupcake batter all over the tray but when he closes the tray it is clean and perfect with the batter in each cupcake holder perfectly.

Other mistake: In the end of the Pinata scene, one of the children looks up at the cat. No one else was supposed to see him. (00:47:10)

Other mistake: When the things clean Mom's dress, the purple goo goes directly onto the couch on the right side of the room. After Conrad asks about the couch, and the camera pans over to the now filthy couch, look at the end table and lamp. They were in the direct line of fire, but didn't get touched. Also, look closely at the lamp. It appears to be a piece of thin lumber cut into a lamp shape.
