If you mean you want to unlock the cat in your Home Instance, you don’t need the Outfit. You just need to stand near someone that uses the skill to call the familiar out. Then feed the cat.
If you mean you want the Mini-Feline Familiar, that’s not unlocked with the Outfit, either.
If you want the skills associated with the Witches’ Outfit, I’m afraid you will need to purchase the Outfit.

Yet. I’m sure it will be offered, again.
