Deliberate mistake: At the market, after the tiger knocks over the pyramid of Hi-C cans, which were set up blocking the aisle just for that purpose, the officer tells Les, "Down that aisle," and the next shot of the aisle is a flipped shot - note the backwards words on the upside-down boxes. Two shots later that same aisle is shown properly, not flipped.
Continuity mistake: After Roy and Johnny's pre-dawn rescue at the market, by the time Roy advises dispatch about the tiger and when Animal Control shows up at the market, it's already past sunrise, but when Les and the officer walk into the store and then when they follow the tiger up onto the roof, it's nighttime again.
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
