Pets Hotel insurance coverage?

What kind of insurance coverage would you need to have if you were starting a pets hotel? These would be domestic pets that are boarded overnight or to cover vacations.

Please suggest what eventualities would be advisable to take out cover for apart from the usual fire or storm damage insurance for commercial buildings.

Is it possible to have vets bills covered if there was an emergency? What if a pet died? Any ideas would be appreciated to help me figure out how feasible an idea this is. Thanks!
