Nice post. Believe it or not, I agree with you more than you realize. Yesterday we had a moth in the house. It was in my daughter's closet and I was worried it would start munching on her clothes, so I tried to catch it with a cup to let it go outside rather than killing it. I'm certainly not as concerned as you, and as I pointed out, I do eat meat regularly, but I try to be kind to any animals that come my way, even insects. Even those we eat should be treated kindly.
Here is an article on LDS teachings regarding kindness to animals.

Probably not interesting to most, but maybe someone would like it.
