You can't do that! That's like playing a board game, then saying 'oh, you can't use dice by the way'.
I like both cats and dogs for different reasons. I find cats to be better for calm, cuddly moments, but dogs make better friends overall, since they're more fun to play with. Also, I like it when dogs can tell when you're sick or depressed, because they seem to be by your side much more often than usual to cheer you up. For example, normally our dog will lay down in the corner on his rug, but when you're sick and resting in bed or on the couch, he'll come in and lay down next to you on the floor. It's so sweet.
