Exotic Direct seems to be the main one.
other companies give you the insurance but use Exotic Direct as the provider.
to be honest.. if your breeding i would assume you have everything you need for your reps...so nothing should go wrong. as long as your providing everything that needs to be provided then your good.
if you want to breed.. make sure you have enough money to back yourself up if things go wrong.. if you dont and your worried for your pets well being... simply dont breed...
there will be a company somewhere that should cover such things i couldnt see from a quick scan on google ( thats me trying to be helpful ha ).
im not trying to be funny there was just saying ha
-good luck in the hunt for a decent insurer.
