Dear Pet Parents,

We are happy to announce WE ARE ACCEPTING NEW PATIENTS!

Missed Appointment/Cancellation Policy

We know your time is valuable, and ours is too. Out of respect for our staff and our other clients, we require at least 48 hours’ notice if you need to cancel or reschedule an appointment. If you do not confirm your appointment with at least 48 hours notice it will be cancelled. As appointments are in high demand, this allows us the necessary time to rebook the appointment time for someone on our waiting list.

After two missed appointments or cancellations with insufficient notice, we will require pre-payment for any future appointments. This amount will be non-refundable 24 hours prior to the scheduled appointment.

Thank you in advance for your patience and kindness.

- Your dedicated team at Princess Animal Hospital
