Nature Lover asked:


I heard that there was a case in horrible animal testing where There was one study where they took a baby monkey from his mother, and sewed his eyes shut, and then stuck a sonar device on his head that constantly let out a high pitched shreik, day and night nonstop.

Is this true? when did it happen? i saw some photos…SICK.
by the way … what is a sonar device? what does it do?

and probably, what was the reason to do it?!

thanks if u can answer some of these x
