You may think that domestic cats are nocturnal, but you'd not really be right. In fact, you'd be wrong, they are crepuscular, which means they are most active
whenever you are trying to work or sleep during the twilight hours around sunset and sunrise.
The more you know, as they say. Here's more that you may or may not know. Shpilkes (also shpiklis and god knows how many other spellings) means pins and needles, ants in the pants, and various other forms of nervous energy which may be exhibited by crepuscular beings in the morning when you're trying to get to work and in the evening when you're trying to settle down to dinner. Or so I hear.
