Creepy 1950 Celluloid Vintage Red Eyed Cat Salt and Pepper Shakers

I love how spectacularly creepy these things are. What’s going on with the red eyes?  Why are their mouths wide open like they are screaming? Did they really need to be tilting their heads to such an extreme angle?  Why are they this bright mustard yellow color? 

 There’s a person in your life that definitely wants these as a gift.
