Thank you very much for your advice. I do cover the seats when we travel but stupidly I have never brushed them before a trip. They shed so much that it always seemed useless. The girls will be getting brushed out very soon and then again before we leave. Too bad one of my girls likes the play "dead bug" when I brush her and she covers herself in more dirt by rolling on the ground. She looks pretty funny but it's sad because she is so timid. I wish I knew what happened to her to make her that way. Thanks again for your help. It's great advice. I'm pulling out all of the blankets and sheets I have right now
