Funny reaction to recorded chin sounds

So my guys get out nightly for hours of playtime. I started noticing that they both were making these barely audible chittery sounds while running around, so I started looking for a sound database to identify the sound. It took me awhile to find one that worked, and after a bit of reading I decided it must be the contact sound, so I played it. Both chins dropped what they were doing and ran to me, popped up on thier hind legs as if to say "you understand us!"



It was sooo cute and funny. These little creatures are so full of curiosity and personality, I just love them :)
