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 Top Cat and his friends are sneaking up to the hideout, you can see that Top Cat's tail is yellow but in the next shot it is now coloured purple.
