Exclusions to Check Before Enrolling
Most of the following items are typically excluded from coverage, so be sure to review the policy terms carefully: congenital and hereditary conditions such as patellar luxation and hip dysplasia; pregnancy and whelping/littering expenses; grooming, vaccinations, neutering/spaying, and dental scaling; pre-existing conditions diagnosed prior to enrollment; and behavioral modification costs. In particular, common feline conditions like stomatitis and chronic kidney disease are subject to a 30- to 90-day waiting period after enrollment. Conditions identified shortly after signing up may not be covered under the initial claim.

If Premiums Spike at Renewal
With renewable pet insurance policies, premiums are recalculated each year based on your pet’s age, claims history, and loss ratio. After age seven, premiums often increase by 10–30% annually. If the cost becomes burdensome, you can adjust the premium by raising your deductible from $10 to $20 or lowering the coverage percentage from 80% to 70%. However, switching to a different policy may result in pre-existing conditions being excluded due to prior diagnoses, narrowing your coverage. Therefore, maintaining your current renewable policy is generally more advantageous.
