Continuity mistake: When Mrs. Otterton is in Chief Bogo's office holding her family photo with both paws, in the wideshots her purse is hanging in the crook of her left arm, but after a brief shot of Judy, when it cuts to Mrs. Otterton's closeup as she tells Bogo about her two beautiful children her purse is gone, then after another brief shot of Judy the purse is back in its place again in the wideshot.
Continuity mistake: During Judy's chase, Duke Weaselton falls beside the large donut sign and the bag filled with flower bulbs lands on the street near the sign, but in the shot of Judy running down the street yelling, "Stop right there" the bag has moved much further up the road beside double yellow road lines, but after Weaselton kicks the donut and it rolls down the street, the bag has vanished from both areas, though the bag reappears after Judy saves Fru Fru.
Continuity mistake: When the landlady shows Judy to her "luxury apartment" note the position of the vertical deadbolt lock affixed to the front door and jamb, but the next morning when Judy leaves for the ZPD, as she unlocks the door the deadbolt lock has moved higher up on the door and jamb (note wallpaper). Additionally, just as Judy opens the door we can see that although the interior deadbolt is affixed higher, its key cylinder on the exterior side is much lower, which makes no sense, but then the deadbolt is back to normal.
Continuity mistake: When Mrs. Otterton walks into Chief Bogo's office, in the shots facing the door there are two screws properly placed on the light switch plate, but when Chief Bogo shuts the door after Bellwether leaves, those two screws have vanished. Additionally, the distance between the door handle and the switch plate changes as well. (00:32:00)
Continuity mistake: The scene where Judy arrives home after working her first day was changed due to earlier events in the film being taken out, however there is still a scene in the final film that was part of the cut scene. When Judy is watching her microwave dinner cooking we see her from inside the microwave. If you look at the shirt she is wearing it is the Pink and Lilac shirt she wears in the deleted scene. This animation was most likely left in due to this small error only being noticed if you were really looking for it and to save time being remade in her meter maid uniform.
