The TNR CON-GAME
FACT: Trap & Kill failed because cats cannot be trapped faster than they exponentially breed out of control.
FACT: Trap & Sterilize (TNR) is an even bigger abject failure because these man-made ecological disasters cannot be trapped faster than they exponentially breed out of control, and they also continue the cruelly annihilate all native wildlife (from the smallest of prey up to the top predators that are starved to death), and the cats continue to spread many deadly diseases that they carry today -- FOR WHICH THERE ARE NO VACCINES AGAINST THEM. Many of which are even listed as bioterrorism agents.(Such as Tularemia and The Plague -- Yes, people have already died from cat-transmitted plague in the USA. No fleas nor rats even required. The cats themselves carry and transmit the plague all on their own.)
FACT: THERE IS ABSOLUTELY *NOTHING* HUMANE ABOUT TNR. Nearly every last TNR'ed cat dies a cruel and heinous death; under the wheels of a car, from other cat and animal attacks, finding environmental poisons, starvation, dehydration, heat exhaustion, freezing to death, infections, incurable diseases, parasites, etc., etc. And if very very lucky being humanely shot to death or re-trapped and humanely drowned (the two most common methods often employed on all farms and ranches to protect their gestating livestock's offspring and valuable native wildlife dying from cats' Toxoplasmosis parasites). This doesn't even begin to count the thousands of defenseless native animals that each invasive species cat skins alive and disembowels alive for their daily and hourly play-toys. The only difference in destroying cats immediately and humanely instead of trapping and sterilizing them first -- then releasing them to the fate of an inhumane death -- is that some money isn't going into an HSUS or SPCA board-member's pocket, veterinarian's pocket, cat-food company CEO's pocket, or a drug-company CEO's pocket. And that's the ONLY difference!
FACT: Cats are a man-made (through selective breeding) invasive species. And as such, are no less of a man-made environmental disaster than any other caused by man. Cats are even worse than an oil-spill of continent-sized proportions. They not only kill off rare and endangered marine-mammals along all coastlines from run-off from the land carrying cats' Toxoplasma gondii parasites, they destroy the complete food-chain in every ecosystem where cats are found today. From smallest of prey that is gutted and skinned alive for cats' tortured play-toys, up to the top predators that are starved to death from cats destroying their ONLY food sources.(Precisely what cats caused on my own land not long ago.)
FACT: Hunted To Extinction (or in this case, extirpation of all outdoor cats) is the ONLY method that is faster than a species like cats can exponentially out-breed and out-adapt to. Especially a man-made invasive species like these cats that can breed 2-4X's faster than any naturally occurring cat-species.
