Binder Park Zoo in Battle Creek is selling a composted mixture of manure from zebra, antelope, giraffe and other animals.
The Battle Creek Enquirer and the Kalamazoo Gazette report the "Zoo Doo" event takes place Thursday and June 5.
Horticulturist Frank Cummins says the zoo has compost available from herbivores that will sell at $25 a load to zoo members and $30 for nonmembers. Cummins says that the price is a deal, since cow manure can sell for around $2 or $3 a bag.
Binder Park Zoo has sold composted manure in previous years. The zoo says it's a "fun and creative way" to raise money and dispose of compost.
It also uses the compost as fertilizer at its facilities, but has extra this year.
