Why are cats and bacon so absurdly popular on the Internet? Why aren't, say, puppies and ham as popular?

According the following infographic by Marketo, cats are popular for a few reasons; among them...

They're funny. Cravendale Milk created a commercial called "Cat With Thumbs," which led to an 8% increase in sales, a 10% increase in brand awareness, and 7 million YouTube views.

They're great for reintroducing brands to Millennials. A British Shorthair cat's photo helped launch Cheezburger.com. Now, the site boasts 3.6 million readers a month and it has raised more than $32 million from investors.

So, how much do people love cats? 30,400,00 Google searches are made for "cat" every month. Also racking up millions of searches every month is bacon.
