And, apparently, a pretty nasty one, too.

The good thing is that we know what caused him to almost die.  The bad thing is that we have no clue how he got infected in the first place.  It could have been anything.

He seems to be suffering no ill effects.  He has a checkup with his regular vet this afternoon, so hopefully all is well in Homerland.  I'd hate for him to kick the bucket before his namesake's movie is released!
