Update:
Ok, so Talon's other test (it was a Urinalysis apparently) came back normal from what they said. Pretty much the vet said finish the prednisone and come back if anything happens or if he acts funny. T_T Helpful. They didn't give us an explanation on why they thought AIHA or why they still wrote "AIHA???" on the end of his paperwork AFTER the urinalysis. They aren't really my normal vet, but my normal vet was 40mins away and I was freaking out and they are the closest I have been to before soo...yeah. Back to my normal vet with us.
Talon is doing better. He is still acting ...weird, for lack of a better word. I don't know if it's from the inflamatin still going down or what, but he keeps closing his eyes or blinking them repeatedly. He can't seem to keep them open normally for more than a minute unless he concentrates really hard.
Otherwise he picked up a ball and tried to get me to throw it for him today, which is a good sign. He's still exhausted and sleeping more of the day, but he's getting better.
So basically, he's getting better, but no diagnosis of what happened. I'm assuming the eyes were a bad allergic reaction, but that leaves the anemia, the brown/grey tongue, and blood in his urine unanswered. So at this point we just don't know. I'm keeping a really close eye on him for any changes and I'm talking through email to the person Stardogs recommended about the possibility of AIHA or not. She has been super helpful.
We will likely go back to our normal vet to let her go over Talon and the information to see what she says, as I respect her opinion a bit more.
If you read all of that you deserve two cookies ^_^
