Continuity: On the scene where Patience Phillips just woke up after robbing the jewelry shop, her hand goes up to her bed and there are a bunch of jewels. She has a ring on that hand, however, we then see as she gets a bag and puts everything in it, the ring is not there anymore. She then finds it mixed in with everything,and tries it on the left and then right hand, where it stays. In the next scene we see as she keeps on putting stuff into the bag, and then finds the necklace, when she brings it up, her hands are visible... guess what? NO RING.

Continuity: When Catwoman first meets the woman with lots of cats, she is sitting on the couch with a bunch of cats around her. The Siamese's that are next to her keep changing from sleeping, to looking at her to one sleeping and one looking at her.

Continuity: In the scene after Patience escaped from the jail cell and is trying to get out of the police station she is standing in front of a window. In the shot facing the window you can see that the window is closed, by her reflection in it, but then when she turns towards the window and jumps out of it, it is fully opened. She never had a chance to open it before jumping out.
