Several years ago I had VPI, but I'm in the states. If they will cover Canadian residents, I would definitely recommend that company! I had a very good experience with them. They do have a limit on what they will cover and how much, however those claims I did make they covered a sufficient amount that I actually saved money, even after you considered what I paid them for the premiums. What I always did was wait until the rat was about 1 to 1.5 years old or so before insuring them, unless I thought they were going to be really unhealthy earlier. That's about the time health problems might start occurring (particularly tumors in females), so that's why I waited - less time spending money on premiums. The only catch with waiting is that you have to insure them before something does happen, so it's a gamble. If they get sick, then it's a "pre-existing condition" and the insurance won't cover it.
