Hi!! This is my first time ever rigging anything, and I kinda need this done on wednesday for a project for my studies so I'm praying someone can help me with this- also my first post on reddit, and English isn't my first language so pls be nice TwT

I'm keeping this model pretty simple due to the time crunch. I just finished doing the Angle X to -30 on the ears, whiskers and face, but realised I have no idea how to mirror so it is the same for +30. I also couldn't really find a tutorial. Is there a way to do this or will I have to do it manually?
