After 29 years of living as a laboratory experiment animal, Vanilla the chimp has finally seen the open sky.
In a heartwarming video posted on YouTube by animal sanctuary Save the Chimps, Vanilla can be seen looking absolutely astonished seeing the wide open world after life in a five-foot-square cage.
Vanilla is a survivor of the notorious Laboratory for Experimental Medicine and Surgery in Primates (LEMSIP), in Tuxedo, New York, where she lived in a garage-sized enclosure. The adorable video was shared at Friday's American Society of Primatologists symposium in Reno by Save the Chimps' primatologist Dr Andrew Halloran.
