Another “pet” that had somehow been domesticated in the Addams Family home was Kitty Kat, a fully-grown lion that wandered through their spacious mansion. Most of the time footage of the lion was just reused over and over again so the production didn’t have to bring this beast onto the set every time the script called for it, so it’s not like Kitty Kat did much during the show’s run. But the mere thought of a bizarre, gothic family having a lion on its property is more than enough to land it on this list.
