My brother just rang to say I will love this Japanese film so I googled and found loads of really good reviews including:
"....The story is as follows: A normal girl named Haru is transported to the world of cats to marry a cat prince who she saved from a speeding truck. That's basically all that I can tell without giving away the film................... those who are cat-lovers will fall in love with the film. ......
Rated PG for frightening scenes, brief sensuality, and language. Suggested for ages 10 and up"
