No, you'll leave a world that, in the words of my late mentor Robert C. Stebbins, will be an "...ordered, domesticated world, reduced in organic variety and filled with people and their possessions."  It will be a world in which "pets" have more rights than people, where Lyme's disease runs rampant from coast-to-coast  because your precious cats have destroyed all the lizards that control the ticks which transmit it, where most birds will be unable to survive below the Arctic Circle, where outbreaks of cat-vectored plague will be a seasonal occurrence, where the beaches are littered with the stinking carcasses of seals, sea lions, dolphins and whales killed by the toxoplasmosis that has contaminated the oysters, mussels, anchovies and mackerels they eat, and in which millions of humans have been blinded and/or debilitated by cat-vectored diseases.  That's just a brief snapshot from the horrific world you will leave behind, if you and your misguided "animal-loving" ilk have their way.
