Brush first, then comb. For long-haired cats, you can start with a wide-toothed comb to unsnarl matted hair and remove dirt and debris. Work in small sections from front to back using a wire brush to remove dead hair, paying close attention to the rump.
Use Talcum Powder
Brush in some talcum powder to separate the hairs. Keep brushing until all of the powder is removed.
Grab a Comb or Toothbrush
Then, use a fine-toothed comb if your cat is shorthaired. Comb a few inches at a time, starting with the muzzle and moving back. Follow up with a toothbrush or rubber brush to groom the short cat hairs on your cat’s face.
Don't Use the Bathtub
Bathtubs are far too large and intimidating. Most pet stores now sell special mesh “cat washing” bags. Alternately, a kitchen sink, laundry sink, laundry tub, plastic dishpan or large, shallow pail will work fine, too. Put a rubber mat or towel on the bottom and fill it with lukewarm water. Hold your cat very firmly, and place them in the water.
Lather and Rinse
Wet them down, starting from the head and working back to their tail. Next, apply a cat shampoo. There are some specifically made for cats. Your breeder, vet or pet store manager can make recommendations. Avoid getting lather in your cat’s eyes or ears. Rinse thoroughly with warm water. A spray hose works best, but a second tub that's pre-filled also can be used.
Dry thoroughly with a heavy, fluffy towel. Keep your clean cat indoors and out of drafts until their coat is dry to the touch.
