On my bucket list - sloth hug! The aquarium in Dallas has a sloth that they take out to meet-and-greet with the visitors. Also the Seattle ZOO you can hug a sloth. The other option is to go to Costa Rica to one of the sloth sanctuaries!
Sloths need you! They may move slowly, but pygmy and maned sloth populations are quickly declining due to poaching, habitat loss and human interference. You can help by joining WWF's “Adopt a Three-Toed Sloth” program.
