Wow! Very interesting how animals can be taught to do things like this! This brings me to the topic of will animals ever reach the intelligence of a fully aged human! With dogs their intelligence is of a child from 2-2.5 years of age, although that might seem quite young the smartest dog on the planet has the same intelligence of a 7 year old! And have you ever heard of Koko, a female gorilla that was taught by animal psychologist Francine "Penny" Patterson to use sign language and she interacted with them and did everything she was told using sign language! They got her pet cats and she mourned for weeks when they died! This is very incredible how animals can sometimes be so intelligent! Thank you for sharing this and please keep us updated on how things go!
