Our cat Dudley is too dumb. He "stalks" the rats in the cage, but they lunge at the bars and he runs away. He'll also watch the squirrels in the backyard, he goes nuts over them. One time he was laying in the grass and had a vole walk 1 foot in front of his face- he never saw it . Our old cat used to catch things a lot- cicadas, baby rabbits, etc. I will leave that up to my mom to tell you, since I was little when she did all of that.
