I'm not sure I understand how you make the connection between the quoting of a religious text with the concept of animals being Christian. All I see is the use of the bible to justify our use of animals, whether for food or clothing or even medical testing. It has nothing to do with the possible religious leanings of your cat!
Like Redhead, I don't have a problem with the use of animals for these things. Nothing better than a nice thick slice of cow, or a juicy pig thigh. Want to shoot a Bambi for its meat? Go right ahead! I don't particularly care for venison, but if you enjoy it, have a ball. I don't even have a problem with those people who enjoy eating dog or cat, though I would be hesitant to try them. We each have our own tastes.
But, also like Redhead, I draw the line at wanton cruelty for its own sake, the sadistic and malicious torture of animals for no other reason than torture.
Medical testing, done properly, is not torture, though you could argue that it is certainly torturous for the animals. Most researchers are aware of the pain they cause, and will minimize it when they can. But if you can save even one human life with animal testing, how can you protest it? Are the lives of laboratory animals, most of which have been specifically bred and raised for that purpose, more valuable than the lives of people? I don't think so!
Sure, many of the tests which at one time were performed on live animals are now able to be done virtually, mainly because of all of the data derived from live animal testing in the past. But eventually you have to test your products on living animals. It's the only way to be sure. Unless, of course, there are some volunteers out there?
