"it is safe to assume that none of you are wildlife biologists or have background in any of the scientific disciplines that pertain to animal behavior"

I was gonna say the exact same thing about you guest...

As a pet owner, I make it my business to know as much as I can about my animal... And to force an animal to behave against it's instinct is ABUSE, plain and simple...

"get off on letting Tabby torture a rabbit, bird, or squirrel to death"

Cat's don't torture... torture implies malicious intent... a cat has no such thing... You're projecting human emotion onto animal behaviour...
