Princess Penelope's Bio

Hello! My name is Princess Penelope and I am the official Meowanger of Customer Purrvice. I have been “employed” with our clinic since 2022 and I take my job very seriously. In my off hours I live at home with my mom, the Practice Manager! I love my second family here and grew up in the clinic coming to work every day. My favorite things to do is steal Dr. Rozenbaum’s chair and stick my toys under the refrigerator, or as my parents say cause general chaos.
