Ferral cats spread disease and spray nasty smelling cat whiz all over everything, and bred more cats, which spray all over everything. And thats a smell that never goes away, on humid days 5 year old cat pee will smell. Those who get outraged at the shooting of wild cats have never had to work in an area where these nasty vermin range. They don't eat the rats either, there is enough food in dumpsters to keep them well fed. The only rats, frogs, birds, etc. they kill are for sport. And not only wild cats spray cat pee all over everything, domestic cats allowed to roam the neighborhoods by inconsiderate owners spray stinkin' cat pee all over everything too. The Western Pennsylvania Humane Society or some other bleeding heart PETA refugees better come rescue the nasty feline pee machines that are sneak into my yard to kill birds or there are gonna' be some more dead cats. Hooray for whoever removed these vile creatures from the face of this planet.
Those who get outraged against feral cats have never worked where nasty vermin like rats are a plague...
If they had, they wouldn't care the least whether the cats killed the rats for food or sport.
They'd only be dam* happy that the rats were dead.
