pet insurance

So, after our recent jaunt down the road towards bankruptcy because of our sick kitty, Brandon and I are considering pet insurance.

I'm wondering if any of you guys have any experience with pet insurance or access to any inside information (Allison? Kris?) about which is best, which have good or bad reputations, etc.

Please share if you have had ANY experience with pet insurance, because we are totally new at this. We don't even know if she would be eligible, as she now has a diagnosed chronic condition (IBD), but it seems like something we should think about, considering the outlay we have already made to get her well again.
