Continuity mistake: As Buddy walks out into the street at the start of the movie when the cat is playing dead, you can see several parked cars on the street behind him. When the van backs up to 'catnap' buddy, there are no parked cars. Then as the van drives off again, there is a different bunch of parked cars in the street.
Deliberate mistake: When the Russian cat sets the bomb on the big metal door, it is set for one minute. Yet this one minute seems to take three minutes to count down. I know it would be boring if it really was one minute, but why didn't they just make it so the cat set it to three minutes?
Continuity mistake: In the scene in the flocking factory when Jeff Goldblum's character is being confronted by the cat leader (Mr. Tinkles) another cat (Calico) is on Goldblum's shoulder. When the shot changes to an angle behind Goldblum, Calico disappears only to immediately reappear when the shot changes back to the angle facing Goldblum.
Continuity mistake: The lawn goes from established grass to freshly laid sod back to established grass. In the daylight scenes you can tell that the grass is growing, probably 4 inches tall, not mowed recently. During one of the night scenes about half way through the movie, you can see that the grass is kind of sickly looking and you can also see the lines around the strips of sod. The next day while the kid is doing his soccer stuff, the grass is back to green and uncut.

Continuity mistake: In the Mason Flocking factory, just after Butch says "I've got to find Lou," the camera shows the window of the office, and the blinds covering the window can be seen hanging at a steep angle. In the shot before Lou pulls on the rope, you can see Scotty's head, and behind it, the blinds are straight.
