Your Home Sweet Home is My Home Sweet Home - S4-E25
Continuity mistake: The Petrie house (where Rob and Laura, Jerry and Millie are standing together bickering) is completely different from the episode "Where Did I Come From?" and a few others.
Continuity mistake: When Benny comes to Top Cat's dustbin at the start of the episode, he first pushes a door bell and then uses a handle to knock on the dustbin. In the next shot, both the bell and handle have disappeared.
