I will have to be honest. I had very limited experience treating exotic pets when I was in practice.
Nationwide is the only company that offers pet insurance for exotic pets in the U.S.
I have read that exotic pet owners, while grateful for pet insurance availability, have complained that it was limited compared to coverage offered for dogs and cats.
I got an email today from Nationwide saying they are now offering comparable coverage for exotic pets now. You can read about it here.
