Will Almighty Allah actually transform the questioner into an animal if they commit sins they believe will lead to such a transformation, based on satanic whispers?

You must repent from all sins, abandon them, and ignore the whisperings (waswas); they will not harm you. And, Allah willing, you will not be disfigured because of these sins. You must repent and seek forgiveness for every sin, abandon it, and regret it; according to the hadith (definition): "The one who repents from sin is like one who has no sin."
