Potsie must have seasonal allergies, because his eyes didn't run during the winter (he's on the same food, so that's not it). His right eye has been running a lot lately. I wipe it off every chance I get, because my vet says that a bacteria that grows in the tears on their fur causes the staining. Keeping the eyes wiped off helps keep the staining to a minimum. I'll be glad when everything is finished blooming!
