Depends on the magazine (and author?), I think. Correct me if I'm wrong. Also, this is the volume version. It was a little bit more censored when first published in Shonen Sunday magazine.
Edit: Looking at this picture I think I found a translation mistake. As far as I understand the last bubble in this panel should be something like "She's washing hersef with the owl", since she's using Kotan as a sponge.
