re: eye goobers -- one of my dogs had the same problem, turned out to be a dry eye. Drops helped a bit but not completely -- the goobers come because the eye gets a bit inflamed and puts out some mucousy stuff.
He's on an ointment called "optimmune" now which seems to work great -- a little bit in the eye each day and it seems to stimulate the natural tear production; no more goobers. Not sure your cat has the same issue, of course, but wouldn't hurt to ask.
