What are some good slogans/phrases to support animal rights?

I’m part of an animal rights club at my high school and we’re thinking about making shirts. One of the ideas for it was to have simply just a witty phrase or solgan on it. Me being the terrible thinker i am, have writers block. So do any of you have any ideas of some that support either animal rights or vegetarianism?
