Lots of confusion going on. Search that page for the word vegan. Nothing. The "Daily Action" page? Nothing there either.
Veganism is the integration of animal rights within an individual's life. It is an indispensable baseline — what someone recently characterized as a "minimum standard of decency". There simply is no animal rights movement without veganism.
How can justice for nonhuman animals mean anything other than, as an essential underlying commitment, becoming vegan? Analogously, how could justice for enslaved humans mean anything other than a commitment to respect the personhood of the enslaved, and stop participating in the system that exploits them?
Additionally, because there is not yet a significant vegan movement, along with the entrenched property status of nonhumans, opportunities for meaningful legal work are severely constrained. Much of the current work, which focuses on "cruelty" and "pets", is counterproductive because it reinforces the property status of animals. To learn about what the focus of any animal rights law should be at this time, I recommend the following presentation by Gary Francione (the preeminent animal rights theorist), and an interview that features him:
