The first step in preparing a Manx for a show is to comb out the loose hair with a metal comb. Then clip the nails. Manx should be bathed the day before the show.
Some coats tend to be greasy.
Use Dawn dish soap to remove the grease from the coat. Next use a good color enhancing shampoo. With each step during the bath it is important to throughly rinse the coat several times to be sure all of the soap is out of the coat. Use a final rinse to assure all of the soap is out. Mix 2 TBS of white vinegar in 2 quarts of water.
