(In order to be official, certificates use my legal name rather than Mirrani, which is my nickname.)
The Red Cross Pet First Aid App has nine quizes available that test your knowledge in CPR and First Aid for pets. I have included my nine badges here. Though they are not an official certificate, they do show I am aware of the basics. It should be noted that if one of these badges specifies Cat or Dog, but not both, it means the quiz was only available for the one species.
