A watery eye discharge. This may become more pus-like as time goes on. Sticky eyelids. Swollen eyes. Redness around the edge of the eyelids.

If the crust doesn’t come away easily, don’t force it or you could hurt the hamster. Instead, go back to holding the cloth on the crust and let it loosen further.

Remember to stop right away if you have any difficulty doing this. Go back to holding the cloth over the eye and wiping away crust, then try again.
