Keito's not doing well

More like not quite right. He's back to being ravenous all the time, and peeing where he shouldn't.  I know diabetic cats have a problem with their bladders feeling over full, and having to empty it, but he went from doing well and normal, to constantly hungry, getting twitchy and getting glassy eyed. 

Have called the vet and made appointment for him.  They will be getting blood and urine samples, and a possible overnight stay for observation.
