## Overview

PawCare is a Flask pet-healthcare application for pet owners, veterinarians, and administrators. Its principal workflow is an owner managing pet records and booking, rescheduling, or canceling veterinary appointments; the application persists the resulting records and sends appointment email notifications. The README also describes account and role management, health records, and appointment reminders. The excerpts show only selected routes and model imports, so some subsystem links reflect documented capabilities rather than inspected route implementations; the repository tree does not include the templates or database configuration.

Main entry points: [`app.py`](https://github.com/estif34/pawcare/blob/main/app.py) (Flask application), [`models.py`](https://github.com/estif34/pawcare/blob/main/models.py) (Application records)
