In 2019, Inman announced plans to step back from The Oatmeal for a while to concentrate on other work including the "Exploding Kittens" television series.

He added that he enjoys making people laugh, and although he can't actually see the reaction of others to his work, he still appreciates seeing the high number of page views that his website receives.
