I switched to Petplan from my other insurance and I regret it. I switched back to my other insurance after making a couple of claims and was very disappointed in the lack of coverage. It also took 3 months for my last claim to be processed (and completely rejected) I called about 10 times, my vet had to send in the paperwork numerous times. I was going to give up on the claim and I should have.
There is better insurance out there.
