Life becomes a nightmare for Skelly when the oddest cat they've ever seen arrives on their doorstep. It's definitely not the Persian cat they ordered... not only is it hairless, but it pees constantly and cries around the clock. As if the neighbors' complaints aren't enough trouble, the vet bills are sky high and nearly bankrupts the newly independent skeleton. But even a mutant cat deserves an owner-- and so, Skelly struggles to fill the shoes of a cat dad with the help of an alcoholic succubus and a devil priest. Meanwhile, a mysterious demon notices their unique pet and wants to steal it for sinister reasons. Can Skelly protect their new cat from kidnappers and other threats within the Devildom, let alone handle living together with it?
