Aurora

Aurora is a quiet, observant Kat, with a great love of nature. She is sweet and caring, who loves the night and the calm and silence it brings. She loves all creatures and being in the company of other Kats, but is also totally content with being on her own. 

Her glow is connected to her feelings; if she is happy, excited or angry, she starts glowing. The intenser the emotion, the intenser the glow. She doesn't glow if she's in a neutral mood or if she's scared, sad, or feeling ill. The glow can go crazy while sleeping, caused by dreaming. Overall, she doesn't have control over the glow, as it's tied to certain neurotransmitters that are released with some emotions, however she can use it as a defense mechanism if she needs to get away quickly.
