Heartwarming / Heathcliff & the Catillac Cats

• In the Christmas Episode/When It All Began episode, "Christmas Memories", Leroy is feeling completely depressed because nobody remembered his birthday, but, it also dawns on him that he really doesn't have any friends. He then gets lured into a party, held by the Catillac Cats, which just happens to be his own birthday party. At the end of the episode, Leroy acknowledges that, despite all the times he's tried to chase them out of the junkyard, they're the closest he has to companions.
• The ending to the episode "Terrible Tammy" where Sonja protects Heathcliff, and even defends him from getting attacked by Tammy. Previously, she thought Heathcliff had been cheating on her with Tammy, but when she later hears about Tammy bragging to a few other cats about the terrible stuff she's been doing, including playing Sonja for a fool, Heathcliff's girlfriend has had enough. Sonja makes it up him by going full-on Action Girl and thoroughly beating her up since Heathcliff refuses to lay a paw on her... since Tammy's a girl.
