Surviving the Sea of Corpses, With the Help of a Cat?

[Zombies] [Pets] [A leisurely pace, but plenty of monsters] [Road-trip adventure]

An unknown virus strikes, and the streets fill with zombies, their flesh mangled and their snarls savage. My horrible mother-in-law and cowardly husband cruelly throw me and my cats out, never expecting that these two cats would become my lifesaving secret weapons in the apocalypse!

[Many kinds of zombie mutations] The ordinary human protagonists rely on their wits to escape danger after danger.

A road-trip story: they stop to rest in one place, then hit the road again.
