Underworld
The mythic Relm of the Dead, located far underground (aka, Hades; Underworld)
Can Kit & Kaboodle hypothetically help someone past the Underworld gates?
The Underworld is guarded by a beast known as Cerberus. Cerberus is a three-headed dog. Cerberus eats the raw flesh of anyone that tries to escape the Underworld. Kit & Kaboodle is a brand of cat food. 
What guards the gates of the Underworld? What kind of creature is #1? What kind of animal is Kit & Kaboodle meant for? Is #3 the same as #2?
