I can't think of the name of this movie HELP?

It's about a boy IDK ifhe's a rat or a cat and he sucks the girls breath away. I can only remember parts and the parts I do remember are really random like the boys mom kills someone with a corn cob and close to the end the boy is like a rat or cat or something and the mom tells the girl he wants to dance with you, then at the end alot of cats come and I think they eat the boy or suck his breath away? I know it's really random, but that's like alll I can remember. Thannks in advance!
