I had to bathe Lucia when she first came to live with me, she had a lice infestation
and I had to use special shampoo. It was terrible! As you can imagine, I had no skin left on my arms, she clawed it all off.
I do periodically wipe the cats down with a clean, damp washcloth, as my husband smokes and I don't want them ingesting any of the residue that might get on their fur. I do think it's important to do that when you have a smoker in the house. (At least he only smokes out in the conservatory)
