Dogs are so much better than cats it's not even funny.
They're smarter (this is a scientific fact),
they're nicer (unless scratching your owners face is a sign of affection to cats),
they play with you (no, mittens, you are supposed to retrieve to ball, not stare at it blankly),
and they can be useful (Tell me, have you ever seen a police cat, fire cat, rescue cat, or any other useful application for cats?)
Also, dogs don't have some stuffty meme thing that involves horribly butchering the English language in a stupid caption for pictures that aren't actually cute.
