Spring is in the air and so is the sweet-smelling aroma of Zoo Doo, Woodland Park Zoo’s exotic, highly coveted compost. The annual spring Fecal Fest kicked off the first week of March.

Zoo Doo is composed of species feces contributed by a variety of the zoo’s non-primate herbivores, such as hippos, giraffes, mountain goats, tapirs and more, and is perfect to grow veggies and annuals.

The Fecal Fest, held each spring and fall, attract local gardeners to enter a bid to purchase the exotic, highly-coveted Zoo Doo and Bedspread that Dr. Doo, aka the “Prince of Poo,” the “GM of BM” or the “Grand Poopah,” has been piling all winter.

Bedspread, the zoo’s premium composted mulch, is available by the truck load. Bedspread is a combination of Zoo Doo, sawdust, and large amounts of wood chips and is used to cushion perennial beds and woody landscapes including rose beds, shrubs and pathways.

Dr. Doo’s private reserve of Worm Doo will be sold again. Worm Doo is worm castings made from Zoo Doo and zoo coffee grounds. An exceptional rich soil and microbial diverse soil amendment recommended for seedlings, potted plants or in the garden, Worm Doo has been pooped once by exotic herbivores and pooped again by compost loving worms.

Due to the high demand for Zoo Doo, gardening fans must enter online to win the chance to purchase Zoo Doo or Bedspread. To enter, fill out the online form here, now through March 27. One entry per person is eligible for each drawing.

Entries will be randomly selected according to supply and demand and Dr. Doo will contact the lucky drawn entries only. Pick-up dates are April 8–29.
