They said he's not got any more neuro issues today and ate lots last night and was bright etc
Still waiting for the vet to asses him today so that he can be picked up.
Obvs I've been doing lots of reading since Tuesday, and first I've ever heard of that "osseous metaplasia" condition of the eyes. I'm pretty sure he has that too as his eyes look similar to a lot of the pics on here of there with it, and the vet asked about his eyes quite a bit at his appt. So I'm going to ask the vet about that today, I know there's no cure but it's good to know.
The vet also said cyst he has is also apparently not a cyst but an infected benign skin tumor. Old age eh!
