Cats have a good sense of sight and an equally good sense of smell. Unfortunately, that sense of smell can be a drawback when you’re trying to attack your owner’s bare feet. Apparently the feet smell so bad that even the cat’s eyes start to roll back in its head, causing it to faint in response.
The next time you ant to punish your cat, try making it smell your feet. As long as your feet smell less desirable than any other part of your body, this could be the cruelest punishment for your cat ever devised.
