Wow, that is outstanding. And they say animals just follow their instinct. Since cigarettes are a rather recent invention of humans I have to conclude that their usages as a fumigating device is a learned behavior rather than instinct. This is impressive!
By the way when as I was reading about this research I couldn’t help but comparing it to the ones involves torturing and killing the animal test subjects to write papers on topics that has zero value for anyone but the so called ‘researcher’. What a difference!
