Herbie had a black face, once upon a time, but he has become a venerable snowy-faced old boy. I was asked how I keep his face so clean, and had to say "Oh, he does all that himself."
There is a reason why I have blankets over much of the furniture, and a reason why I mostly wear old jeans at home. After each meal, Herbie will walk the length of the sofa one way, sliding his face along the surface, then turn and wipe the other side of his face, again along the entire length of the sofa. If I am standing up, he will then come and wipe his face against the back of my legs. I've learned to change out of my work clothes fast.
Holly, despite being a dainty girl, is much less bothered, and going out with legs covered in tomato sauce is normal for her.
