My pet is a cancer survivor thanks to Trupanion and West Veternarian. He had a miraculous surgery (Dr. Szentimrey), chemothrapy and is now on oral drugs. The staff at West Vet are fantastic in the oncology unit (Dr. G. Maudlin) and the techs (Jenn and others).
And Trupanion have been absolutely true to their word. No limit on claims, deductible once, 90% (except taxes and consultations). They've proceesed claims with West Veternarin on the same day and provided us with clarification and information right away.
