Yes - - I can relate exactly to what you are talking about. Sometimes I have to turn off the news if there is a story about a person or animal suffering terribly. It really gets to me.
And all of those ads about animal abuse make me want to cry sometimes.
There are many animal welfare organizations, and I think they are places in need of donations or support. I've given money to them before, though I wish I had more I could give.
I think if it's helping even just one animal, it is all worth it.
