Probably only 3 or 5 days after he was abandoned because he was so little and fragile. My wife and I heard the meow sound on the way home. We waited for several minutes and finally found him at the corner of a pile of trash, dirty, eyes closed with slimmy thing, almost dying.
Maybe it’s just poor lighting and the kitten has brown eyes?
Not that case. The iris was changing at that time, that’s why.
