the hunter never sleeps

[smith2267]

the ears of the cat, do never sleep
Alert instead for things that creep
What's this?? to his feet, the cat doth leap
Be it friend or foe, with malice deep?
But no, but scarce the noise does peep
But by his senses, doth his owner confound 'er;
'Tis but the can opener, announcing flounder.

"Kitty is keeping tabs on his territory even when he snoozes. Kitty has an understanding of which noises are normal and which are not. Noises he used to, like the dryer or dishwasher running, won't disturb his slumber. However, if he hears something that is out of the ordinary he'll wake up alert to check out what disturbed him. Sometimes this can be something that signals danger -- or perhaps you simply filled his food bowl."

Or if you a 'cat-owner' you wake up fast if
you hear a sound like the cat puking.
