Another issue I have with my adopted stray (please also see my "Budda belly" thread)
is his chronic watery eyes.
He showed up at my doorstep with full blown Upper Respiratory Infecton, worms, and watery eyes.
The discharge was not thick, not yellow or greenish. It is clear and often (not always) stains brown-reddish brown on the tissue when wiped off. it's definately not dirt by the color of the discharge.
His eyeballs themselves are clear, never bloodsot, and the vet couldn't find any scratches, lesions.
He went through a 7 day course of erythromycin, then two 7 day courses of terramycin. If for nothing else but to assist with co-infection and be palative. These treatments did not help.
My understanding is that herpes of the eye, and less often clamydia of the eye, for cats has the tell-tale brown watering.
So because the antibacterial courses did not clear it up, I gather it was not clamydia (bacteria), but is in fact herpes virus.
I also all this time have been adding lysine to his food, as I have read that it may help his body keep the herpes virus busy and eventually get it under control.
But although he's become so much healthier in other areas, this pesky eye problem persists.
I sure would like to solve this for him.
By the way, I suppose there's an outside chance it's allergies, but he had it in the middle of winter til now, and has no other allergic symptoms. He doesn't scratch or paw at his eyes, only to clean his face normally.
