Name That Trauma:: Dexterpie on a Black & White Shapeshifting Witch

Hello Kindertrauma,

I'm trying to find a movie that I saw as a child. It had two witches in it. The ugly witch was good and the pretty witch was bad. The pretty witch could turn into animals and ended up burning the ugly witch's house down. I'm pretty sure the movie was in black and white. Any help would be appreciated, I've been looking a long time!
