It's time for the September edition of the Smithereens Cartoon Caption Contest, which pits the dogs against the cats.
The rules are simple: The Sun's Mike Smith provides a cartoon with a blank word bubble. You tell us what it should say.
All you have to do is submit your suggested caption in the comments below by noon Sept. 17.
We'll pick our five favorite entries, and then you can vote for the winner Sept. 20 - 27. We'll announce the winner Sept. 30.
You can see last month's winner here.
