Hi Kim-
Is he using the litter box normally? If you are not sure, you need put him with a box and not let him go outside until he goes. I'm concerned about a urinary tract blockage which will produce many of the symptoms of what you are seeing. Please let me know if he seems to be straining to go, makes several trips without producing anything or is licking his genitals excessively.
