To see if cats can hear underwater.
We expect that cats can hear under water.
One cat.
One swimming pool.
One large concrete block.
Rope.
The cat was trained to come to the sound of an electric can opener.
After training, the cat was tied to the concrete block and lowered
into the swimming pool.
The cat no longer responded to the electric can opener.
The hypothesis was not confirmed.
Cats cannot hear under water.
