Use the

Priority list as Kitty's do not have an actual rotation
Keep Faerie fire up at all times
Keep Savage Roar up at all times - duration depends on combo points - see below
Keep Mangle up at all times ie every 12 seconds - Unless there is an arms warrior or another feral druid
Keep Rake up at all times ie use every 9 seconds
Keep Rip up at all times - Duration depends on combo points
For the rest of the time (should you have any) Shred until you get as many combo points as needed
When you have 10 seconds left on Savage Roar AND Rip and you have some combo points - Ferocious Bite - Do not do this if you do not have plently of time left. The damage done by the bite does not add up to the damage lost by losing Roar or Rip
It is not essential to wait until 5 combo points for Savage roar. i usually hit mine after 2 combo points as I have 50% crit rating and combo points come at a decent rate. If your crit is in the 35-45% range, I would go with 3 combo points minimum so you have time to get Rip up with the Roar buff.
Remember to use Bezerk during times that you will not take aggro from the tank. either wait until tank has a lot of aggro or do it when no aggro is present.
