Do you remember a movie about killer cats?

I vaguelly remember a movie where a group of people were on a boat and a cat is going around on the boat killing people, (like eating a man under a blanket) Towards the end, I believe the cat is seen floating on a suitcase and lands in a group of other cats? Also I remeber a cat being decapitated and the head kept chasing people (in a barn I think) Please help with this corny movie. I would love to show it to the family!!
