Sanrio, the creator of Hello Kitty, was unhappy with a Dutch ruling in a copyright case against its famous feline character’s rabbit friend Cathy.

An Amsterdam court last week ordered Sanrio to halt production and sales of Cathy merchandise in the Netherlands, Belgium and Luxembourg after finding the Japanese bunny too closely resembled the Dutch character Miffy.

Miffy (left) was created in 1955, while Cathy (right) has been marketed since 1976 as one of the friends of Hello Kitty, a character that made its debut in in 1974. Sanrio is considering filing an appeal.
