Add animals to the list of issues that petitions can be written in about.

I came to this site to sign a petition for animals and found there is no way to just look at animal rights and well being.I searched keyword animals and got two petitions that are really not about them.
We are the voice of the animals. We need a place to tell the White House how important they really are to people.There are so many atrocities throughout the world towards animals. The White House should know how many people want things to change for them.
