We believe this unique reporting approach is worthy of sharing with our CNN.com readers . Refugio Aviarios del Caribe , Costa Rica ( VBS.TV ) -- Sloths are fantastically weird animals , the junkies of the jungle who seem to spend their lives either nodding off or scratching and occasionally eating a bean or two before drifting back to what looks like a blissful sleep . I 've always been a fan of sloths . They 're wonderfully freaky , yet perfectly adapted to their slow arboreal lifestyle . Their nerves have even evolved to react slower so they do n't flinch at loud noises , making them nature 's most chilled-out animals . They have very few natural predators and the only time they 're vulnerable is when they leave the trees once a week and descend to the ground to poo . This behavior has befuddled scientists for many years . One of the theories is that their solitary lifestyle affords few chances to hook up with the opposite sex and these toilet stops are a good way to meet other sloths . See the rest of `` Sloths ! '' at VBS.TV . But evolution did n't prepare sloths for the power lines and roads that now crisscross Costa Rica 's jungles . The babies of mama sloths who have been run over or zapped by electricity wind up at the Aviaros del Caribe sanctuary in Costa Rica . It 's the world 's only sloth orphanage , home to more than 100 very sleepy urchins whose lives have been saved by legendary sloth whisperer Judy Arroyo . If you fall for these animals like I did then you can join the sanctuary 's volunteer program . Trainee sloth wranglers get to feed the sloths and help exercise and potty train the babies . The sanctuary runs on donations and volunteers , so you can do your bit by helping these vulnerable creatures whose jungle home , some say , is being slowly destroyed by pesticides , sold off to U.S. real estate agencies , and sliced up by roads and power lines .
Sloths have very few natural predators . They are not a threat to humans, and they don't need us for food or shelter. Aviaros del Caribe is the world 's only sloth sanctuary .
