See these eyes so greenDespite the fact that cats can have a wide variety of eye colors, green is especially associated with them. In fiction, green eyes are often found in characters with feline Animal Motifs, Cat Girls, shapeshifters who turn into cats or Kindhearted Cat Lovers. This association comes from a variety of superstitious beliefs about cats. Because All Witches Have Cats, a witch will most likely have a black cat with green eyes as her Familiar. There's just something mysterious and eerie about green eyes glowing in the dark. The colour also helps underline the association with magic and the supernatural or untrustworthiness.
