When I was a final year student at the Dick Vet in Edinburgh, there were nursing students doing their practical components there, including in the exotics animal hospital. I believe there was an additional zoo option, an extra year of schooling I believe, offered. I *think* they were from the UofE nursing program, but I don't know for sure. If you contacted them they could probably confirm that for you.
Sorry to not be more help and good luck!
