The Cornstarch Trick: For stubborn mats in Angora or Lionhead fur, rub a little cornstarch into the knot. It helps the fur slide apart so you can comb it out without pulling the skin.
The Cool Blowout: Once a week, use a hairdryer on the 100% COOL setting. This blows the fur open so you can spot "pin mats" at the skin level before they become huge tangles.
Safe Trimming: If you must cut a mat, always slide a comb between the bunny's skin and the mat first. Bunny skin is as thin as tissue paper!
