Millie-Light, small, striped, silver tabby she-cat with blue eyes, short fur, and a torn ear.

Millie once was kitty-pet and a loner, but don't let that fool you! She is a fierce warrior of ThunderClan. During her kitty-pet days she met Graystripe, they fell in love and quickly became mates. The cats travelled back to the Clans, and they both became ThunderClan warriors. Millie refused her warrior name, saying there was nothing shameful in her name, she kept the name Millie, but still became a ThunderClan warrior. Soon she was expecting kits. The names of the kits were, Blossomfall, Briarlight, and Bumblestripe. During the 4th series they were apprenticed. Millie is known as an overprotective mother. When the terrible accident happened, giving Briarlight disabilities, she became over obsessed with her. Millie was outraged that her daughter had such a terrible fate. She helped Briarlight everyday, with exercises or encouragement. Millie ended up neglecting her other kits, and they were not happy. Millie had normal warrior duties, and fought for the well being of her Clan.
