There is no verified universal monthly price for “life insurance for a pet” in this guide. A meaningful mortality quote would need the eligible animal, role, value, covered causes, underwriting information and state. A health-insurance quote would answer a different question.
Ask for a written proposal describing the actual product and its exclusions. If a search result only offers ordinary accident-and-illness coverage, it has not answered a request for an animal death benefit, even if the page uses the word life.
