I don't know anything about pea eye. I read the Guinea Lynx pages about it, and it says it's not really a big concern. However, it also mentioned that it could be caused by a heart condition. I've dealt with a heart pig before. I'd do it again, but... I kind of what to have a realistic idea of what I may be getting myself into if I were to adopt her.
Here is the link to her page. If this isn't allowed please delete. I've never posted a link before, so I'm not sure the rules.
Impactions are manageable. If they are neutered, less of a problem and they could be housed with a female.
