My cat Lucy is the only inside animal we have, so needless to say, she is alone most of the day. I know that she sleeps a great deal-what else is there to do, right? She has always slept with me, and slept what I thought was through the night...for the past 4 or 5 days, she is up rambling all hours of the night...is it possible that she has insomnia? I have had her for a little over a year. She was a stray when we got her, and was grown...I haven't noticed this kind of behavior before, and it not only worries me, it is keeping me up!
