No noticeable improvement

We've been doing the serrapeptase for three weeks now.  The eye still looks horrible, all around the ulceration the orb is bright red.  I'm not sure if that's a good thing or bad, it may be the body trying to heal itself.  He still usually acts like he is feeling fine...playful, good appetite, affectionate, but I don't see any indication that the enzyme is digesting any of the scar tissue that's keeping the eye open plus I see what looks like further deformation around his snout.  I do believe that the serrapeptase is making it though the stomach and in to his system, we are seeing small amounts of blood leaking from the eye which I believe is due to the anti-clotting properties of the enzyme.  Since yesterday Pika hasn't been very interested in the wet food we give twice a day, he still likes his treats (Pit'r'pats and greenies) but we'll have to get his weight more frequently to make sure he isn't declining.  It may be time to look at other options in addition or instead of the serrapeptase, but as soon as we feel we can't keep him comfortable and pain free we will have to let him go.
