MY CAT

He cries, Beepers all night in of all places..
the bathroom?!  Well, I usually get up hold him
tell him everything is ok.. HE SCREAMS in there
pretty loud.. I get worried, because I live in
an apartment too...

WHAT CAN I DO FOR HIM?  He isn't old, hes only 5
and wasn't hurt.. He has tons and tons of toys..
and plenty to eat.. Any help, is always appreciated!
