It’s obvious that she doesn’t understand what I say (although she knows her name and a few other words). But she also seems to know the difference between proper actual human talking and just random words strung together. She seems to pay attention when people talk to her, not at all when they say sentences constructed from random words.
This isn’t a very good experiment but it has the makings of an interesting hypothesis. And OF COURSE I’m going to experiment on my cat. Who doesn’t?
