Question Regarding Particles on Mirror

I’ve modeled a cat by sculpting one side and mirroring it for the other side. Everything went nicely until I tried adding particles (for fur). The fur would only appear on the original side, and not on the mirrored side. Can anyone help?

Thanks in advance.

You need to apply the mirror modifier

I’ve figured that much in sculpting the entire form. I’m asking about the particles.

Maybe I’m misunderstanding- could you elaborate?

In the mirror modifier, click the ‘apply’ button

Oh, I see now. Thank you very much.
