Does White color has to be an infection? My last rabbit, had them daily, not at the corner, but mostly at the lower eyelid, it's soft, but clearly normal dirt accumulated thru out the day, and he had those daily for his entire 4.5 yr. of life. Although she died of liver cancer, but never had any problem w/ his eyes.
Having said that, Little Happy is a bit different. Al my other bunnies has the dirt at the corner of their eyes daily. Little Happy almost never did. It's mostly underneath his lower eyelid. So daily, I have to massage the upper and lower eyelid gently, so the soft white stuff come out.
