somewhat progression..

On my issue, i've decided to deal with more cat and dog cruelty. there's such a wide variety on what to do, it's overwhelming. i need to figure out where i could do some volunteer work, and what i would be doing. As of finding community leaders or legislators, i'm not really sure on how to go about that yet. i need to research leaders that have somewhat something to do with animals, or any type of cruelty i guess..
