Actually, if the owner of the cat files a complaint with animal control and an administrative proceeding is brought attempting to remove your sister's dog from the jurisdiction (or to euthanize the dog) the homeowner's insurance will not defend the administrative proceeding. You will need to hire a private attorney to assist you with this. If a civil suit for damages is brought by the owner of the cat, the homeowner's insurance will defend the civil lawsuit.
This is not to be construed as legal advice. I do not have an attorney client relationship with you.
