A few months ago I felt 2 bb sized lumps by one of my cats mammary glands. I took her to the vet and it was recommended we do surgery as they are usually cancer. I had a unilateral mastectomy preformed and had to submit many claims to trupanion for the surgery, and then multiple rechecks. All of my claims were processed extremely fast (the last claim literally taking 5 hours from submitted to processed). I am very pleased with the service provided by trupanion. I have also called multiple times to talk with customer service and everyone is always so friendly and helpful and was concerned about how my cat was doing after surgery. It did turn out to be cancer (not a very aggressive form) but I know trupanion will be there if we have more issues in the future. She is doing great and the cancer was completely removed!
