While I too love animals, aren't human beings just animals as well?...
And isn't anything and everything we do natural?...
The problem with the Greenies is they are so bereft of human contact that they lose themselves in the 2002 cats back home!!...
Now while I "own" or more acurately room with a cat, I will never stop eating meat and I'd be afraid to keep the occasional meat snack (ie... Roast Beef) from the animal; namo Blinky, don't ask me I adopted him from the NY City Sanitation Yard in Coney Island and that's what they called him, in fear that he might decide to take a chunk of John-Boy!!
All I can tell you is we two animals get along well!
Now if the Greenies were real they would get out there and hate humans for merit, not just in theory!!
