Pet Nibble Subscription plans are based upon a specific term (e.g. monthly, quarterly, semi-annually, annually). Your selected plan will automatically renew and charge the credit card on record for the selected term amount (see 'Amount Billed' above). The date you subscribe will be the start date of your term. Billing occurs at the beginning of each term for the full amount of the term selected. Subscriptions may be cancelled at anytime during the term. Once cancelled, your plan will continue until the end of your selected term. Partial term refunds are not available. Please contact us should you have questions.
