But cats are not nocturnal, they are crepuscular, most active at dawn and dusk. As long as you don’t try sleeping in past dawn there’s not really a problem with a mismatch in human and feline sleep schedules. Our cats sleep almost all night and almost all day!

Our guys are most certainly up at night, but in the morning at least one is on the bed, and the other snoozing elsewhere.

I am usually up and about before them. When they come in to the office and bug me to feed them around 0830 or so, I know the outside kittehs are waiting for breakfast as well, 99% of the time.

They are nocturnal, but seem to have internal clocks that synch with humans especially with feeding times.

So THAT'S why it sounds like a hurricane fighting Godzilla in my kitchen at 5:30 AM in my house!!!
