A solid cartoon that throws the spotlight firmly on its neatly plotted story, 9 January 2009
Author: ( from Lincoln, England

Robert McKimson's 'The Unexpected Pest' is a neatly plotted little cartoon with some unusual twists and genuine laughs. When Sylvester's owners realise that they don't need him now that he's got rid of all the mice, the cat has to seek out a mouse to save himself from becoming homeless. Threatening him with being eaten unless he follows his instructions, Sylvester uses the mouse hundreds of times in order to convince his owners that they have an infestation. I won't spoil the fun by elaborating further but the final few plot twists make for some very funny moments indeed. 'The Unexpected Pest' moves at a fairly leisurely pace and isn't much to look at but the script is great and McKimson wisely throws the spotlight firmly on the story. It's best the first time you see it but, with the delicious knowledge of what's to come also enhancing the fun, 'The Unexpected Pest' stands up to repeated viewings too. It's a solid cartoon and it's always a pleasure to see Sylvester without either of the twin drag factors, Tweety or Speedy Gonzalez.
