According to the BBC, some mad scientists (okay, they didn't say "mad") here in California hooked up something to a cat's brain and could, thus, see through its eyes. "Theoretically, by fitting a transmitter onto the headset wiring of the cat, it would be possible to send it down a blocked pipe, for example, so that it could beam up pictures of where the trouble was.... Similarly, birds could be trained to act as real spies in the sky, and dolphins could check out the enemy's submarines." Once again, the future arrives before we expected it.
