Clinging and climbing at Sloth Sanctuary of Costa Rica, these baby sloths demonstrate their adorable squeaks. Animalist visited the sanctuary for Sloth Week in June, 2014 to interview sanctuary founder Judy Avey-Arroyo and sloth biologist Becky Cliffe about their work rescuing and rehabilitating injured or abandoned sloths.

Plus, a note from the sanctuary:

A sloth’s heart rate rapidly increases (tachycardia) from stress if held by strangers. They are also exposed to foreign microbes and allergens, which can compromise their immunity. For their well-being and yours, do not touch Sanctuary sloths or sloths being exploited for photos along the road as you travel in Costa Rica.
