/like like the title says I saw it like 15 years ago don’t know if it was a movie saw it on TV it wasn’t English it was I’m guessing Asian Language movie had a Gibli looks to it so yeah there was this little boy with his littl brother (sister) who where living with their grandma or caretaker they had a (black cat) who go went evil started eating the people including the grandma (who I think was a wizard) oh and the end of the film was bizzar the protagonist boy (age like 10) made a friend with a worm I think and in the end the worm and all

the people the cat had eaten where walking in like a rainbow road towards the ocean. Wierd but amazing movie.
