Much like home or auto insurance, a pet health policy can help provide peace of mind — kicking in to help cover costs when your cat or dog has an injury, faces a serious health problem and, in many cases, goes to the vet for routine wellness care. Veterinary medicine can do amazing things for pets these days, but the costs for scans and other treatments can quickly add up. When you have pet health insurance, though, you don't have to choose between costly care and your sick pet — the nose-to-tail comprehensive protection can help you do right by your furry friend.
