Selina Kyle: Ok, Intimidate me, bully me if it makes you feel big. I mean it's not like you can just kill me...
Max Shreck: Actually, it's a lot like that.
Trivia: The shot where the monkey walks down the stairs to give The Penguin the letter from Batman took many shoots to complete, because Danny DeVito's makeup frightened it. According to one interview DeVito gave with Jonathan Ross, on the first take, the monkey even tried to bite him... right on the groin. Thankfully his padded suit prevented any bodily damage.
Question: After she falls, what exactly makes Selyna Kyle go nuts? And what is she trying to do to her apartment?
Chosen answer: She just died, and came back to life. The shock drove her mad. She really isn't doing anything but destroying it.
Answer: The film keeps it ambiguous. There are two ways to look at it. Scenario A- She literally died and is brought back to life by the alley-cats somehow, adapting some of their traits. Or... Scenario B- The trauma of falling and sustaining a head-injury, along with her paranoia after Schreck tried to kill her, has driven her mad, and she uses her connection with cats to build a new persona. (Which is supported by the fact that all the things she claims "kills" her with each of her "nine lives" wouldn't actually have killed her. Ex. Her one fall is broken by the kitty-litter truck. Max doesn't hit her in any vital organs when he shoots her. Etc.) Her destroying her apartment is her lashing out at all the things she used to hold dear- her vision of a normal life, etc. It's symbolic of her purging the past and embracing the future. (Plus, oftentimes when people throw fits, they'll smash stuff up).
