I brought two from my daughter's that were matted with cat hair. I shooked them out and then hung them on the clothesline for the day. What didn't come off then, I washed them and rehung them on the clothesline and I would say I got 99.4% off so I'm happy. I love animals, but, the grandkids and I have allergies and the critters should not be allowed all over the house, bedreooms should be off limits.
