In "Birthday Surprise", after Cindy-Lou asks Tom to bring her a mouse (referring to Jerry), Tom's jacket and bowtie disappear when he runs across the street to his house. When he is shown again leaving his house after entrapping Jerry and putting him into a flower bouquet, his jacket and bowtie reappear.
When Tom peeks into the window of Cindy-Lou's house, his sclerae of his eyes are white instead of yellow.
