Factual error: The "Russian Blue" isn't a Russian Blue at all. Russian Blues have pointed faces and green eyes. The flat faced, orange eyed kitten is a British Shorthair AKA British Blue. (00:39:35)
Factual error: When the Russian Blue is in Luke's house, there is a shot where Butch is tangled up in the telephone wire but it should actually be mirrored since it was the reflection in the cat's eyes.
