My guinea pig YinYang has always been amazing at finding her cage. Here’s a quick demo. This only shows he going for maybe 15 ft. but she can find her way from three rooms away. She just follows along walls and furniture ’til she’s back in the main room, which she knows, and then she bolts to the cage, mostly because it’s home to her beloved food :) BTW, this video is from Jan. 2006 but Ms. YinYang is still around and is 6 yrs. old.
