I am a very new rat owner and am a little concerned about one of my new boys. He is almost 3 months old, and I've had him for almost 6 weeks. Recently (within the last 2 weeks) I've noticed he looks wet around his eyes, or stained somehow. I've read about porphyrin which can build up around their eyes, but in all the pictures I've seen it's looked almost blood-like and stayed relatively close to their eyeballs. I haven't come across any articles that have this kind of staining/wetness. It's interesting to me because there are clear, distinct lines. Is this something I should be concerned about? He has been acting normally, is still food-motivated and exploratory, and I haven't noticed an excessive sneezing (though again I'm quite new, so I may not know what counts as "excessive").
The first picture here is from about a month ago, with no staining. The second two are more recent. Please let me know what you think!
