Meanwhile I had such a scare last night. I found myself awake sometime around 2:30. "Hmm, where's Luckie?" I asked myself. I fumbled around and found her on the pillow next to my head. I turned to look at her and was surprised to find she wasn't looking at me, since she always wakes up if I touch her, wake up, etc. Well, she was o-u-t. In fact, she didn't even seem to be breathing! I shook her and nothing happened. I swear, I thought she'd had a stroke from a blood clot caused by her operation or something and had just died. I shook her for 3-4 seconds before I saw some breathing, but she still had her eyes shut. I started calling her name and gently shaking her more and finally she opened her eyes. She was all muddled. I think she was in the midst of actual true sleep, not just a nap, and possibly it was deeper than usual due to the events and drugs of the previous day. Poor kitty!
Afterward I remained so panicked I had to get up. I then noticed that the little light I'd left on by the dresser was out. I'm sure the light bulb died and that's what woke me up, not the cat "dying." Well, I hope anyway! I seemed to take a long, long time for me to fall asleep again.
