At PetFirst, we want to care for your pets from puppyhood throughout all nine of their lives. Unlike some of our competitors, we don't have an upper age restriction for enrollment. We allow dogs and cats ages 8 weeks and older to enroll in our pet insurance plans, making it easier to afford veterinary care for the long haul. Though your premiums may increase as your dog or cat gets older, your pet's coverage will remain the same and never will be reduced or limited due to age. With a PetFirst Lifetime medical insurance plan, you are insured for any hereditary, congenital or chronic issue that rears its ugly head later in your dog or cats life.

So, as your dog or cat gets older, their rate of cancer increases as well. Our plans cover cancer treatments, as well as the diagnostic tests like x-rays, blood tests and biopsies (as long as the cancer isn't showing symptoms or diagnosed prior to the effective date of the policy). Cancer can be expensive, and catching it early can help decrease your treatment costs.
