A Wholesome Helping Of Cool Cats Who Call The Shots In Their Respective Households

Hey there, cat lovers. We would like to make a statement. Cats are the coolest species to ever exist in the history of the world. A dramatic statement, yes, but an accurate one, definitely. We think it has to do largely with the feline inclination to dominate, but in a cute way. Our cats run our households, and they weigh around 12 pounds each. It seems absurd when you think about it, but that's the reality that we cat appreciators live in. 

Being cool is about not giving a hoot and marching to the beat of your own drum, that's why we think cats take the cool cake. Also, can we talk about how they can dictate the entire lives of us humans, swindle us into financing their suspicious pyramid schemes, and feed them half of our rations every time we open a tuna can? There needs to be some discussion around this topic. In the meantime, enjoy a silly series of cool cats being their goofy selves.
