Need help with macro

I had a simple attack macro for my druid cat form:

/castsequence [stealth] pounce; reset=25/combat/target rake, rake, claw, claw, etc.

This worked good for a long time but then I decided to add mangle (cat) to the mix and the sequence would get hung up on the mangle:

/castsequence [stealth] pounce; reset=25/combat/target rake, mangle (cat), rake, claw, claw, etc.

this version didn't work and I don't know why. I tried "mange" and "mangle (cat)" and "mangle(cat)" but that didn't help. Barring that I may have made some slight typo somewhere I don't see what's wrong. Any ideas?|||try this

/castsequence [stealth] pounce; reset=25/combat/target rake, Mangle (Cat)(), rake, claw, claw, etc.
