Well I'm glad the BMs, the fluids, and the cerenia made him feel better! Sorry about your sleep schedule....
FYI, it's pretty normal for a cat to be off their food if constipated. Spooky used to get constipated from time-to-time, and not eating at more than one meal consecutively was how I knew that was the issue. I would use miralax OR aloe vera and slippery elm bark powder to help. Using egg yolk lecithin seemed to really help regulate things, but she still got constipated, just not as frequently. There have been no issues (the longest run she's had now without getting constipated, knock wood) since putting her on the digestive enzymes.
