So He's Not A Stupid Kitty, Just A Lazy, Spiteful One

 

Researchers in Japan arrived at this conclusion after performing experiments with twenty house cats. They played recordings of the cats’ owners’ calling to their pets in whatever cat-talk voice they typically used. They also played recordings of three strangers calling to the cats, using the same words. 

To quantify the cats’ reactions, the researchers recorded how often cats moved their head, tail, paws or ears, or whether they meowed or dilated their pupils. While the cats showed a significantly greater response to their owners calling their names than to strangers doing so, they did not bother to get up in either instance, the researchers found.
