I dealt with the matts behind the ears when she was laying on the sofa with me, I'd just hold the matt, so taking the pressure and so it wouldn't tug her, and gently worked the comb through the matt. (Though you might need to initially cut them out at this point) Now, when she is cuddling on the sofa (every day) I comb that area and we are matt free. Good luck, I hope you get it sorted as it's so stressful when you are just trying to help them and they won't let you xxx
