The cat has wised up and knows that the red dot is coming from somewhere else. He also knows the noise of the pointer, I'll pick it up and he'll run over to bat at the end of it. He's all "fuck this red dot shit, I know you are the one making this happen" while the dog is all "red dot? red dot?! I want the red dot!" I love putting it on the wall and she'll go to bite it and smush her snout up against the wall.
My cat will do back flips for that silly red dot! Runs in circles for it - I think I have a video somewhere. He also passes out panting! Tuckers him out!
