In Kumamoto Prefecture, Japan, Momo the cat and Moko the rabbit like to take a walk with their human every day. (Youth.cn) They are inseparable. The neighbors call them "Brother and Sister."

Momo watched Moko grow from a tiny baby rabbit and is very protective of him. When the human takes a walk outside, they tag along. These two buddies have brought a lot of fun to the neighborhood.

Sometimes, they get a visit from another cat that lives nearby according to Youth.cn. Moko is a bit shy, and always follows his best friend Momo for that extra companionship.
