Hi everyone, I'm just wondering the best way to remove an unknown sticky residue that has formed a clump with fur on my rescue bunny's face. He had this when we adopted him a week ago and it hasn't improved. I have no idea what it is, just that it's sticky and maybe a big greasy. No colour to it. I was thinking to try dawn dish soap? Or does anyone have a better idea? Unfortunately it's next to his nose in the whisker area, otherwise I would shave it off. Thoughts?
