Getting the dynamic hair styled just right can take quite a bit of detailed work.
Bump and displacement maps will not give you good results for up close or mid distance renders.

If your goal is to learn it, go for it! However, if your goal is to get a nicely furred kitty into a render in a limited amount of time, Tiny's furred cats is a great product!!!

Postwork is also an option, but again, nicely painted fur can take some time :)
