As you can see, in the photo on the right this Persian kitten has major facial staining and stains on the ruff.  The facial staining is primarily caused from the oils and dyes in food, the water bowl and eye discharge.  With a flat face or an extreme faced Persian, eye discharge is a normal occurrence.  Regular application of facial powder also called grooming powder will reduce staining of the Persians coat.  

When grooming your Persian cat, remember that consistency in grooming plays a big factor in  how your Persian cat will look. Grooming powders work by absorbing stains from the areas it is applied to as well as future moisture and stains will be absorbed by the powder. For example to keep eye stains to a minimum on the Persian cat's face and the eye area you can apply grooming powder to the areas affected by eye drainage and discharge.  Grooming your Persian can be a fairly easy process if you powder the affected areas on a regular basis. 

The Persian kitten pictured on the right was bathed after regular usage with the facial grooming powder.  As you can see this is the same kitten that was picture above and the facial stains he had in the previous photos are nearly gone.  With regular usage of the grooming powder you can remove a majority of these facial stains very easily. 

One thing to remember when grooming your Persians face is that you will want to be very, very careful working around the eye area.  When first starting out with the facial grooming powder, start slowly as this may be a new thing for your kitty. 

Another tool that works great when grooming your Persians face is a flea comb. 

Although it's a little hard to see the detail in the photograph, but this is what is referred to as a flea comb.  A flea comb is available at most pet supply stores.  A flea comb has two sides of very fine teeth for combing.  When grooming your Persian cat or kitten, the proper grooming tools will make grooming a lot easier. 

Remember that your Persian cat will not be accustom to this when you first start the process so please be patient with your Persian cat or kitten.  Also note, it is very  important to be careful when working around the eyes of a Persian especially with a comb. You don't want to catch a tooth of the comb on the corner of the kittens eye.
