If we didn't know that they had been bred to be domesticated for much of human history, we would probably think that cats were engineered in a lab somewhere to make the ideal adorable pet. With their massive eyes, fluffy tails, and those cute chirruping sounds that they make, they're almost impossible for any animal lover to resist.
Of course, that illusion is shattered when you take into account the reality of living with the average housecat. When your entire house starts being treated like a jungle gym with endless places to vomit and/or mark territory, you quickly realize that these creatures are as much agents of chaos as they are cuteness. At the same time, this is why they provide a great inspiration for many memes. Cats are crazy little guys, and neither their owners nor the meme makers would want it any other way (most of the time).
