Unheeded Warning

Is the unheeded warning trinket good for cats or for bear tanks? I know the 321 agility is awesome, but the proc with increasing weapon dmg..does that translate into kitty or bear paw attacks?
Last time I looked into it, since 4.0.6 change to unheeded warning, I believe fluid death and unheeded warning are the best first tier trinkets for a feral dps. The weapon damage bonus does translate to mangle and shred. I could be wrong though. I wouldn't recommend it for bear though.
It doesn't do that much for bear - the additional damage doesn't buff your Savage Defense.
It's the Best-in-Slot trinket for cats though.
For one, the permanent agility is nice to have for both, but the proc is much better for Cats:

It buffes Paw attacks.
For Bears, it also buffs Mangle. As Tangedyn wrote, it doesn't buff anything else, especially not SD, so the proc is almost useless for Bears.
For Cats, it also buffs Mangle, Ravage, Shred, Maim, Swipe and (lol) Claw. That's why it's BiS for Cats.
As stated above, Fluid Death and Unheeded are the two BiS until heroic raids. Then I'm pretty sure Essence of the Cyclone replaces Fluid Death.

For bear, you're going to be much better off taking Fluid Death as one of them for sure. Tia's grace is also good, The TB resistance trinket helps out on fights with predictable magic damage. Once you hit raids the Symbiotic worm and Vial of stole memories are pretty nice.
