# MagTag Cat Fed Clock ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/097/839/medium800/circuitpython_cat_fed_clock2-resize2.jpg?1608022067) Did you feed the cat this morning? Would the cat tell you if you did? Of course not – food is an indoor pet's main source of entertainment. Using MagTag, we can create a clock that sets itself and allows you to save a reference to the last time you fed the cat – simultaneously maintaining your pet's healthy weight, and your sanity. Bonus: it's compatible with dogs as well. ## What You'll Need Featured ### Adafruit MagTag Starter Kit - ADABOX017 Essentials [Adafruit MagTag Starter Kit - ADABOX017 Essentials](https://www.adafruit.com/product/4819) The **Adafruit MagTag** combines the new ESP32-S2 wireless module and a 2.9" grayscale E-Ink display to make a low-power IoT display that can show data on its screen even when power is removed!
