A young animal enthusiast was given an interaction he’ll never forget when an otter mimicked a toy of itself as a child moved the stuffed animal around on the aquarium glass. Jacob Cauich could not believe his eyes as he moved his toy - adorably named ‘Otter Otter’ - around on the glass, with the animal on the other side mirroring its every move. For a number of minutes, the river otter at Oakland Zoo, California, glided around in the waters as four-year-old Jacob choreographed its every move. The youngster’s parents, Kimberly and Mike, were shocked as the scene unfolded, capturing it on video on June 4. Having initially seen Jacob playing with Otter Otter, the animal became intrigued and decided to approach the four-year-old as close to the glass as possible. Jacob’s favorite animals are otters, and so for the rest of the day the youngster was “all smiles,” according to Mike, 33.
