I have recently insured my cats for the first time and purchased wellness coverage. I took one of my cats for a checkup as well as treatment for a pre-existing condition. When I submitted the claim, I indicated it was for a wellness checkup only. They caught and notified me of the mistake, and then politely reminded me when I was... well, lazy... about resubmitting the corrected form. Once they got the correction, they paid the claim really fast. Really, really fast, actually. One doesn't usually expect such conscientious customer service from an insurance company!
