Cat Planet Cuties
Cat Planet Cuties is a twelve episode (plus OVA) anime series based on the Japanese light novel series Asobi ni Iku yo! (あそびにいくヨ!?, lit. "Let's Go Play!") by Okina Kamino with illustrations by Hōden Eizō and Nishieda. The series is of furry interest because of the amount of Kemonomimi characters.
Human protagonist Kio Kakazu encounters a girl with cat ears at a memorial service for his ancestors. She calls herself Eris and claims she's an alien. Before long various agencies are searching for her and Kio finds himself protecting her from harm.
