I truly don't have a single complaint. I can't say it's the cheapest insurance but as they say, you get what you pay for. I insured my fur-baby days after she came home. She was diagnosed with a liver disease a mere 2 months later. Trupanion paid for everything as promised, fast and without any arguments about what was covered or not. They continued to do so test after test, procedure after procedure. They checked in on her. They fixed errors in reimbursement almost the second they were identified. Best of all, they didn't increase my rates exponentially because I dated to use the insurance I purchased. I have not been let down by Trupanion yet. As her disease progresses, I know I can at least have one less thing I need to worry about and I couldn't be more grateful. It's heartbreaking enough without having to think about the financial component.
