I think my list of possibilities at this time is Xanthus (zan-thus), Echo, Atlas, and Sirius. Right now my vet's office has named him "Lizard" and it's become a huge joke over there lol
Some more photos of him. He's on baytril for his infections and today finally there is no more bubbly spit! I'm so happy to see improvement. And he's gaining lots of weight despite being a little sick, so he's doing really well. Oh and I've tentatively settled on Atlas for him, but it could change if I fall in love with another name lol
