I am looking for the title of a movie involving an evil cat that is vomitted out of a good cat. The evil cat is on a cruise ship or boat and attacks and kills the passengers when it is vomitted out of the good cat. I think the movie came out in the 80's. I tried to look it up on Google and you tube but had no luck finding it. If you know this movie please let me know. Thanks.

Uninvited (1988) (http://www.imdb.com/title/tt0096341/)
