You can cast spells in non-human form.
Prerequisites: Animal Form or Metamorph (powers)
Benefit: You can cast spells while you’re in a non-human shape due to the effects of the Animal Form or Metamorph powers or any spell that alters your physical body such that you could not reasonably perform your verbal/somatic components. You substitute noises, gestures, grunts, or mechanical sounds.
You can also use any material components or focuses you possess even if they have melded within your current form. This feat does not allow you to use magic items while you are in a form that could not ordinarily use them, and you do not gain the ability to coherently speak.
