Make sure she gets used to having her nails trimmed at a young age. You should also take her for long rides in the car, and never give her cat treats or anything that might spoil her. A weekly bath is a must as well.
Hope this helps.
Whatever would a kitty need a weekly bath for, unless you're looking to dry out her coat of its natural oils? Why would you want to accustom her to long rides in the car? And what's wrong with the occasional cat treat, as a reward for letting you clip her nails and such?
