my kitten Fiur (4mo) has been waking me up like clockwork at 5:30 every morning. Our older cat Nova (2yrs) gets riled up and goes along with him. Before we got Fiur, we slept like babies. We free feed them, and I make sure he has food before I go to bed. I work night shift, and on nights I'm not working I stay up until 1 or 2am, so my 5:30 wake up call is getting a bit draining. I make sure to play with both cats before I go to bed, but it's not helping! Any suggestions?
