APA does not list "cartoon" as a specific example in its manual, but here are some ways to approach it:
If found in an online periodical (ex., newspaper) or periodical database:
Cite as you would a periodical article, but include a description [Cartoon] after the title of the cartoon (if there is one). If the cartoon does not have a title then include [Cartoon] after the date.
