Ok so it has been about 5 days and now he is totally off Fromms and on the Acana Grasslands. I noticed this morning his eyes were very wet, to the point of being wet above his nose and between his eyes. I also noticed that he was losing some fur in this area as well and had some eye gunk (clear) below his eyes. If I rub my finger between his eyes, it is covered in little furs. I also noticed his eyes are red/pink. How long does it typically take for the new food to take effect.
