I have Nationwide (of course, it's the only one that insures exotics in USA). I get a discount thru my job. They have covered things easily enough so far (ear infection, ringworm,) but I am concerned w/ my newest pig they will say his arthritis is pre-existing and won't cover it. I clearly asked my rep if he would need a vet visit before enrolling, and they said no. So I waited til it was active and took him in.
My biggest issue is their website is 100% trash and slow to load.
