Rat Toons is a comic that features slapstick comedy antics of animated animal characters.
Slimer was amused with a cartoon cat in Issue #5 and wanted to share in the laughs. First, he tried to tell Ray Stantz but he was too busy practicing with his tuba. Second, he tried to show Peter Venkman but he was too busy working out on a stationary bicycle. Winston Zeddemore was too busy working on Ecto-1 and Janine Melnitz was too busy finishing work on her computer. He went upstairs to Egon's lab but disrupted an experiment. After being yelled out, Slimer sulked the attic and continued reading Rat Toons.
