My goodness, no a cat doesnt do much of anything, but there is no way that I think a dog is smarter. As the owner of both a cat and a dog, Ive seen both. The dog serves me, it will protect my house, it will get my paper(yes we trained it to actually do that) and it will basically do as I say. The cat on the other hand lays around all day doing nothing. I feed it, I pet it, I make sure its litter box is clean, I give it somewhere nice to sleep, and yet it never does as I say. Basically the pet/human world has an order. The dog serves the human, the human serves the cat. Basically the cat must be a genius to have gotten a cushy job like this.
