Predatory Swiftness macro help pls

I am trying to get

/cast [mod:alt] Regrowth; Ferocious Bite ( the basic macro )

to not shift me out of cat form when get finished with my proc. If i am sitting still and spam the Predatory proc it pops me out of cat form. I have tried all sorts of macro combos to no avail.

Thx for any help

/console autoUnshift 0
/cast [mod:alt] Regrowth; Ferocious Bite
/console autoUnshift 1

THANKS Elvenbane for the response i will try tonight!
