As you can probably tell from several of our recent blog posts (including the termite board, the browse feeder, hanging juice bottles outside the caging, and frozen troll dolls), we’ve been working really hard to come up with unique enrichment puzzles for the chimps. Last week, Jessie from the Center for Great Apes visited, and told us about Boomer Balls. Boomer Balls are non-toxic, heavy-duty polyethylene plastic balls. At the Center, they drill holes in the boomer balls and freeze Gatorade or juice inside. She says the apes at the Center love it and we suspect the Cle Elum Seven will too. So, for this month’s Chimps’ Choice item, we’re asking for Boomer Balls. Help us enrich the chimps! Send us a 4 1/2″ ball, a 6″ ball, a 10″ ball, or a 10″ snack-n-trim in the next month, and we’ll send you something special in return.
