Also, Flier is actually a figment of imagination, made by a small crippled kitten named Meeku. Meeku doesn't know, but Flier used to be a spirit, and now takes care of Meeku, since his mother left him and his father died. Flier works as a guard and watchdog over Meeku, also working as a good influence. This is in Meeku's dreamland, where they meet and play every night. :)
