He ended up with about an inch of his tail being amputated on Monday.
He's had a hard time adjusting. I can get him to eat, but he won't open his eyes all the way and is lethargic. It's possible the infection in his tail spread into his bloodstream. I'm going to start him on antibiotics to see if that helps.
I may give him Critical Care too when I tube feed Raydan to see if I can help him get extra nutrition.
