A young woman's sexual awakening brings horror when she discovers her urges transform her into a monstrous black leopard.

Irena Dubrovna: I like the dark. It's friendly.
Irena Gallier: I'm not like you.
Paul Gallier: That is the lie that will kill your lover.
Oliver 'Ollie' Reed: Oh, you can tell Alice anything, she's such a good egg she can understand anything.
Irena Dubrovna: There are some things a woman doesn't want other women to understand.
Oliver 'Ollie' Reed: You cold?
Alice Moore: A cat just walked over my grave.
Irena Dubrovna: That's Lalage - the perfume I use. I like it, perhaps too well. Maybe I use too much of it, living alone like this.
Oliver 'Ollie' Reed: It's hard to describe. It's not like flowers exactly. It's - it's like something warm and living.
Dr. Louis Judd: Why would she wish to harm you?
Alice Moore: Because I'm in love with her husband.
Woman at pet shop: I can't imagine!
Irena Dubrovna: You're very wise, you know a great deal, yet when you speak of the soul, you mean the mind, and it is not my mind that is troubled.
Dr. Louis Judd: What a clever girl. All the psychologists have tried for years to find that subtle difference between mind and soul, and you've found it.
Irena Dubrovna: Will you have tea with me in my apartment?
Oliver 'Ollie' Reed: You make everything so simple!
Irena Dubrovna: Oh, it's alright. It's just that cats don't seem to like me.
Woman at pet shop: You can fool everybody, but laudie dearie me, you can't fool a cat. They seem to know who's not right.
Paul Gallier: I didn't think you were ready, but you are. I knew it when I saw you with HIM.
Irena Gallier: Who? Oliver?
Paul Gallier: You want to fuck him, don't you? You dream about fucking him! Your whole body burns, it burns all along your nerves, in your mouth, your breasts... you go wet between your legs.
Irena Gallier: Stop it!
Paul Gallier: Every time it happens... you tell yourself it's love. But it isn't. It's blood. And death. You can't escape your nightmare without me, and I can't escape my nightmare without you. I've waited a long time for you.
Oliver 'Ollie' Reed: [Looking down at Irena's lifeless body in the form of a panther] She never lied to us.
Minnie: My goodness, don't nobody like chicken gumbo?
The Cat Woman: [In Serbian] Moia sestra! Moia sestra!
The Commodore: Look at that woman over there.
Doc Carver: Looks just like a cat.
Irena Dubrovna: What should I tell my husband? Naturally, he's anxious to have some word.
Dr. Louis Judd: What does one tell a husband? One tells him nothing.
