I came across this in relation to pet rats:
"The light and noise will most certainly not bother the rat because rats are non-associative animals and they will not mind the noise and light of the television."
Now, as far as I know "non-associative" means something that does not associate one thing with another. Rats, however, are very intelligent by nature, which by definition means they should be pretty good at making associations. It seems that here the phrase is used to describe their perception rather than their intelligence but I've never seen it used like this and I'm not quite sure what is meant by it (neither could I find anything in the dictionary). Could someone please clarify.
