All I can say is that we’ve had videos similar to this one before, and they show that raccoons (Procyon lotor) are a lot smarter than we think. (See, for instance, here, here, and here.) Below is the YouTube caption of a video posted just two days ago:
Occurred June 16, 2016 / Camdenton High School, Camdenton, Missouri, USA
“I am a Police Officer in Camdenton Missouri and was working security one evening at the local High School. I saw the mother raccoon on the wall with one of her babies as she was attempting to get her other baby over the wall. The mother raccoon leaned over the wall as the baby held onto her legs so she could reach out and grab the other baby and pull him up. Great example of a mothers love and teamwork!” -Chris Williams
Now how did the baby at the top figure out to hold its mother’s legs? Another question: why aren’t scientists studying raccoon cognition as avidly as they study porpoise cognition?
