Midwestern home gardeners can get a good deal on a truckload of exotic animal compost from a zoo in southern Michigan, reports thetimesherald.com.

Binder Park Zoo, in a bid to raise funds for the zoo, is offering composted poop from giraffes, zebras, antelopes and other herbivores at $25 a load for members and $30 for non-members.

Only herbivores' waste can be used for gardening; carnivores' poo carries pathogens that can be harmful to humans.

“It’s through gate admission, events and -- like Zoo Doo and many others -- that allows us to remain open and to feed and care for our animals, many of which are endangered or threatened. Zoo Doo is a fun and creative way for the Zoo to receive funds to help care for our animals and dispose of our compost,” Kari Parker, marketing manager at Binder Park, told thetimesherald.com.

The animal dung is thoroughly composted, according to the zoo, which means it's odorless -- or rather, it doesn't smell like fresh poop.
