Puppy Bowl XI -- We're Prepared ... For a MAJOR Crapshoot

Only one team of dogs will win the eleventh annual Puppy Bowl ... but they'll all have to poop at some point -- and Animal Planet has their cute butts covered.

This year's event will feature 85 pups, 21 kittens and 5 Nigerian Dwarf goats (the cheerleaders) -- and producers prepared by purchasing 315 poop bags ... as well 1,200 puppy pads.

The animals will also have their own personal assistants -- 65 puppy escorts and 50 volunteers -- plus they've got a whole lot of food on deck.

Halftime performer Katty Furry got the real celebrity treatment though ... her outfit was crafted by a famous pet designer whose made expensive outfits for Paris Hilton and other celebs. They also extended an invite to Katy Perry to their pre-game party.
