Hello! My Guinea pig Chuck is 6months old and I noticed this sore on the bottom of his eye. It doesn't seem to be affecting him at all, no scratching, weeping from the eye, closing eye etc. Info that may or may not help: he lives with another Guinea pig, Ned who is just under 2 months younger than Chuck and they recently got a new cage. Could anyone please tell me if I should treat the eye or if it will heal itself. Thank you
sorry for so many photos but it looks different from different angles!
