When my Smokey was old & sick she would sleep very deeply and be difficult to wake up, but never when she was young. My Jordan will be 4 in May & he scared the daylights out of me last night. My Mom called at 3:30 AM (that's a whole other story don't even get me started). Jordan was asleep between my feet, I touched him & he didn't move. I picked him up & he was limp like a wet noodle. Well I had to say his name a couple times before he woke up. He finally did & then curled back up & went back to sleep. In the morning he was fine, woke right up & started begging for food. He just made me so nervous last night, anyone else have a cat that dose that to them.
