> happiness actually derives from having cats

Not if you're part of the massive destruction of wildlife wrought by these biodiversity annihilators masquerading as cute pets.

'As an invasive species[1] and superpredator,[2] they do considerable ecological damage.[2] In Australia, hunting by cats helped to drive at least 20 native mammals to extinction,[3] and continues to threaten at least 124 more.[3] Their introduction has caused the extinction of at least 33 endemic species on islands throughout the world.[2] Feral and domestic cats kill billions of birds in the United States every year, where songbird populations continue to decline.[4]'
