Maybe it would help you,
DEM, to clarify to yourself your position on eating meat. I don't think that it has to be an all-or-nothing proposition. Here are my personal thoughts about how I treat animals and/or how they should be treated; maybe something like this, modified to fit your own viewpoint, could be helpful to you. And of course, if you decide to go vegetarian, I certainly wish you well.
Companion animals: I would never intentionally harm my (or anyone else's) pet. If I adopt a pet, I make sure that pet is well-fed, is emotionally nurtured, and receives appropriate medical treatment throughout its life.
Livestock: By this I mean domesticated animals raised for the purpose of generating a product (meat, eggs, milk, hide, etc.). Animals of this type should receive adequate nutrition and medical care while alive. The living conditions should be as good as practically possible. Their deaths should be relatively quick and painless.
Wild animals: I do not hunt, but if I did, I would never hunt for sport, nor would I be purposely wasteful. (That seems to me to take the animal's life a bit
too lightly.) I would not lay traps (such as for rodents, etc.) unless not to do so would endanger people and/or I could do so with little detriment to the animals themselves. I would not try to capture or keep a wild animal, except perhaps for rehabilitation. If I severly injured a wild animal (hitting a deer with a car, for instance), I would arrange to have it put it out of its misery.
Some other things you can do that might make this a more palatable choice for you are buying free range chickens, pasture-fed beef, etc. Also, have you considered donating to the
Humane Farming Association?
