Kali Belladonna is a cat Faunus from Menagerie, and she is Blake Belladonna's mother. She is first seen in "Menagerie" answering the door and giving her daughter a heartwarming embrace. From http://rwby.wikia.com/wiki/Kali_Belladonna
As a cat Faunus with black hair and yellow eyes, Kali has several physical features in common with her daughter. She has short hair and three gold piercings on her cat ears - two on her right, one on her left. She wears a black hakama and sandals with white tabi socks. Over her outfit, she wears a black shrug with a long right sleeve and a short left sleeve with gold leaf trim along the opening on the front. On both arms, she wears long, black arm warmers that extend to the middle finger. The left one has a purple band tied around the top and a pair of gold bangles around the wrist. Around her waist is a black and gold sash that trails behind her, with a gold flower-shaped buckle at the end.
