This was Julie Newmar's final appearance as Catwoman. She wouldn't portray the character again until 2016's Batman: Return of the Caped Crusaders.
If the living room to the model house looks familiar, it's because it is part of the set used as Brit Reid's house in The Green Hornet (1966).
The Gotham City Suburb of Norchester is a name pun on Westchester County, a New York City Suburb.
In Julie Newmar's last scenes as the Catwoman, the villain tries to seduce the Caped Crusader while wearing poisonous perfume (but her scheme is foiled by Batman's use of Batplugs in his nostrils). Next after returning to prison, she declares to Bruce Wayne (her parole advocate) that her heart is for Batman. When Eartha Kitt assumed the role the next season, all dialogue from this episode (and previous ones reflecting desire for Batman) were completely ignored.
After Commissioner Gordon informs Bruce about Catwoman's return to crime, and moments later Batman mysteriously knows all about it, Bruce and Dick head for the batpoles. This is the only time in the entire series that the viewers see them descend from the study and land in the batcave all in one shot. No transition effect. No commercial break.
