The Basilisk petrified Mrs Norris and the other students.
In the movie Chamber of Secrets Hermione and the reporter kid Colin,Filch's cat Mrs. Norris and nearly headless Nick were also petrified and there was one other kid petrified too.
Argus Filch's cat, Mrs Norris, was petrified. None of the cats died though.
Mrs. Norris is the name of the cat that is owned by Mr. Filch, the caretaker. In the second book, Harry Potter and the Chamber of Secrets, Mrs. Norris was the first one to be petrified by the basilisk. Harry was blamed by Filch for petrifying his cat.
The title of chapter 9 in Harry Potter and the Chamber of Secrets is 'The Writing on the wall'. The topics in it are Mrs Norris, Filch's cat, being found petrified and there being writing on the wall in blood. There is more to it but I suggest you read the whole book in order to understand it properly.
Argus Filch.
Mrs. Norris was not killed, just petrified. The creature that did it to her was a baslisk, which is a giant snake. When you look into the eyes if a basilisk, it kills you. But, Moaning Myrtle had flooded the bathroom, so there was water on the ground. Mrs. Norris only saw the basilisk's reflection, so she was only petrified. :-)
Several of Harry's friends and classmates are turned to stone throughout Harry Potter and The Chamber of Secrets. In order, the Basilisk petrified Mrs Norris (Filch's cat) by looking at her reflection in a puddle of water, coming from Moaning Myrtle's bathroom. Next was Colin Creevey, who looked at the Basilisk through his camera. Justin Finch-Fletchy was petrified by seeing the basilisk through Nearly-Headless Nick (who was petrified, in a sense, because he could not die again). Finally, Penelope Clearwater and Hermione Granger were petrified by looking at the basilisk with a mirror (Hermione had, by this time, discovered the monster's identity and wanted to warn as many people as possible.
The following were petrified:Mrs Norris, who is Argus Filch's catColin CreeveyJustin Finch-Fletchley and Nearly Headless NickHermione Granger and Penelope Clearwater.
In the English version of the Chamber of Secrets with 251 pages i'd say the climax is on page 104 when Harry, Ron and Hermione (well Harry) hears the voice in the walls and they they find Mrs. Norris petrified.

Hermione Granger and Penelope Clearwater were the last to be petrified.
