This is an update from my previous thread, I guess. For the past 3-4 weeks, Moses has been being very inactive. He's been hiding in his hide, doing nothing else. He's usually very active, coming out at 11:00 on the dot to be held. Not only that, but he hasn't been eating. The first time I offered him food, he struck, missed, and acted terrified and hid again. The second time he didn't care at all (though that may have been my fault - I had to offer a different species of rat because our usual reptile store was closed). Today I changed his water and decided to check on him. I took him out of his hide and I first noticed that his eyes seemed... dull? Pale? Not as much when he's in blue. I thought they might have been retained eye caps so I gave him a soak for about 5 minutes (he then escape from the tub so I just put the humidifier in my room). While I was holding him then I noticed he was making a whistling sound every 15 seconds or so. Then I was worried. I put him back in his enclosure and left the humidifier on. Respiratory infection? Shedding? Nothing about his setup has changed except a different climbing branch.
