Metlife takes the cake when it comes to pet insurance discounts. If you have two to three pets, choose Metlife's family plan to get anywhere from 29% to 37% off—way better than the 5%–10% multi-pet discount offered by other pet insurance companies. The only catch is that you can't add more than three pets. Plus, anyone who purchases a plan online automatically gets $1 off their monthly premium.
