There are many things cats are well-known for, and near the top of that list is definitely "cats are jerks." We love our cats with our whole hearts, but by golly those same fur-balls of kitty delight give us a run for our money.
The typical cat doesn't like being told what to do (or what not to do,) nor does the typical cat abide by household rules. Even the most well-trained cat has their moments of defiance, it's simply the cat's nature.
Actually, come to think of it, maybe it's the kitty's natural state of existence that draws us so closely to them? Purrhaps.
