Grooming is an important part of caring for a Persian. That is fairly obvious but it seems some people don't do it often enough (perhaps through pressure of time in this modern world).
The key, it seems, is to be pro-active. That means always finding the time to groom. Little and often should be the motto. Go patiently and never to harshly.
And if you start early on with your new little adoption/partner then he/she will get used to it and learn to love it.
It would seem that it can't be stressed enough that when you adopt a Persian whether she is a rescue cat or from a reputable breeder, you need to be fully aware of the long term responsibility involved.
A cat will change your life to a fairly substantial extent, much like a child.
If in doubt go to a good rescue center and foster for a while, working in partnership with the center and see how it goes. It's a big step and not to be taken casually.
