This little one acts completely feral unless you make the "mommy greeting kittens" noise at them. When my phone isn't making them unsure they will come charging to the front of the cage for attention by the second trill.
You can see the body language change in the ears with the first and second trill real well
Showed this video to the speaker doing the intra-cat aggression lecture as she does a lot of stuff with cat behavior, and offered it for her use for to the easy to show changes in body language and she was super excited! *squirms happily*
