Male or female? If it's a girl, maybe name her after a famous red-head (like Lucille Ball). If it's a male, maybe something having to do with a tiger...names are elluding me right now, but those are just some ideas.
Here's some ideas for orange cat names (based simply on the color since you haven't shared any other bits about the cat!)...
Ketzia (ket-ZEE-ah) Hebrew a cinnamonlike bark
Lilly-low1 a bright flame, British
Lokilani (loh-ke-LAH-nee) hawaiian small red rose/heavenly rose
Lollybanger gingerbread with raisins
Souri/Suri Persian red rose
Souzan Persian burning, flaming
Aerugo (ee-ROO-go) Rust
Pirro (PEER-roh) Spanish name 'with flaming hair'
Questzal (KEHT-sehl) large green/red bird worshipped by Aztecs; Guatamala national emblem
Alani (ah-LAH-nee) Hawaiian orange
Iiwi (ee-EE-wee) Hawaiian bird with brilliant red feathers
Keegan or Kegan - gael - irish liitle & fiery one
I'm going to get a little orange tabby Maine Coon... his name shall be Mr. Pumpkin... and he shall be fluffy and sweet and fat... yes... yes my plump little Pumpkiny goodness... how I'll love you! *squeezy* *pet* *pet* *realizes she's been holding her bookbag* Uh? Darn those kitty fantasies! I'll just have to play with my little fluffy sweetums Halifax until I get him a couple friends.
You should name him/her Pumpkin... it's such a cute name! But in the end it's up to you. *goes back to day dreaming*

Haha -- that's an oximoron isn't it??
Anyway -- when I name cats, I try to imagine them having a say in it. If I pick a name and I can see them with an unamused look on their face saying "yes...my mom named me Fluffy...wanna make something of it?"....chances are I have picked a silly name. Think about your kitty having to tell his friends that his name is Floofypants. Think about it...would YOU want to be named Floofypants? Not likely. You'd be the kid at school getting wedgies and flushies from upperclassmen every day. Give your kitty a name that doesn't make it sound like a little pink stuffed animal with glitter all over it's head.
I was watching the animal channel today and I saw a woman who named two bear cubs after presidents -- like taking their middle name or last name. I thought that was pretty cool, provided she didn't name them Kerry or Bush! (...sorry 'bout that...)
