Hahahah, yeah, honestly I wouldn't call my cat smart. He's kind of a dummy. But he is the sweetest, friendliest, burbliest dummy you will ever meet. And very persistent when it comes to food (unless there is another cat around to bully him away from it, in which case he caves and just sits there sadly watching them eat, the dork).

But yeah, some of them are eerily clever, and definitely able to scheme. ;)
