Well, on my Level 70 Feral Druid, i mostly use Kitty form for playing, though i am ok to do offtanking when needed, but fulltime tanking is a big fat NO!.
When in cat form, here is what i do: (please note, i have yet to do any raids, so this might not work on them due to their insane immunuities to CC or anything that stops their actions)
1: Prowl (stealth obviously)
2: pounce (5-6 second stun + a nice bleed dot)
3: get behind and Shred x2 (if specc'ed to lower cost of Shred)
4: Mangle (this adds a debuff to the mob that increases all bleed damage to the target by 30%)
5: Rip (this gives another Bleed Dot and combined with the pounce dot, it gives nice dots with mangle)
6: mangle 3-5x (depending on crits)
7: Ferocious Bite or Rip again (depending on how much health is left on the mob you are fighting, if still a decent amount of health, rip is the one to do, but if close to death, then Ferocious Bite is best.)
Thats worked for me in the past, but due to too many demands to tank fulltime, i have recently stopped playing the druid.
Also, i advise to cause as much damage as possible, cause dots don't count towards the DPS meter, only instant and direct damage does, ie. mangle, Ferocious Bite etc.
Cause before i figured that out, i was always ******* at for being low on the dps meter, if the dps meter counted dots as well as direct damage, the druids and affliction warlocks dps levels would skyrocket on the meter. :)
