I have been with Trupanion (formerly VetInsurance for about 2 1/2 years. I have found their claim processing to be very timely and have never had a problem with them denying my claim. But, my premiums started at about $37/month and have gone up every year. The latest increase is from $47 to $58. And, my vet clinic has not increased their costs, so I find it hard to believe that these premium adjustments have nothing to do with either my pet aging or claims I have made.
