All the typical cons of working at a non-profit and they stem from the lack of money. Money is tight, very tight. You don't go to work at PETA for financial stability, you go bc working for animal rights is in your soul. And because animal rights are a part of your fabric, you will be on the clock 24 hours. You aren't asked to be, but it really does take over your life. That can be a pro for some people, I suppose.
