Two days later, Mijbil escaped from my bedroom as I entered it, and I turned to see his tail disappearing round the bend of the corridor that led to the bathroom. By the time I got there he was up on the end of the bathtub and fumbling at the chromium taps with his paws. I watched, amazed; in less than a minute he had turned the tap far enough to produce a trickle of water, and after a moment or two achieved the full flow. (He had been lucky to turn the tap the right way; on later occasions he would sometimes screw it up still tighter, chittering with irritation and disappointment at the tap’s failure to cooperate.)

Explanation:

 

The otter quickly got comfortable with the area, so he went to the restroom by himself and tried to open the faucet with his paws. Surprisingly, by starting by turning the tap in the appropriate way, he was able to open it just enough to get a trickle of water and then more to get the full flow. Other times, he would twist it more tightly by moving it in the wrong way, only to be dissatisfied when water did not flow from it.
