I have two female rats they, are both under a year old. My rat azula is doing fine. she had a respiratory issue a while back, but she's regaining weight and starting to be herself. Now that she's better and being a normal rat I noticed my other rat zuko is weird. She has dried porphyrin chunk's on her eyes. She's very skinny compared to azula. And she has been squinting quite a bit. Google is a rabbit whole so I wanted to get advice from more experienced rat owners before calling a vet (this is the clearest photo I could get of her)

Hi and welcome to the forum!
It sounds great that Azula is getting better.
Regarding Zuko, I would take her for a vet checkup if you can. Squinting is a common sign of pain in rats so she may be feeling quite unwell.
All the best with her.
