Pets triggers doorbell in "people only mode"

I just installed 2 video doorbell pros and am majorly disappointed that my cat keeps triggering an alert at all hours of the night. It is in people-only mode. We chose these because of that specific mode and my parents bought cameras and spotlights too thinking the light wouldnt turn on unless there was a human. Now I am afraid they will turn on all the time as well because the doorbell does.
