This is Amethyst.
Amethyst was left in a box as soon as she could eat solids, and was blind longer than most kittens, so never knew her mother's face. She can see well now and is a strong and fiercely loyal cat who stands up for anyone in trouble. Even having to fend for herself in her younger days was easy for her, since she loves finding a way out of tricky problems. She's best friends now with the other gem/jewel-cats and is super happy to have found her true, if not blood, family.
