Keeping the sharp tips of your cat's claws blunted will also help make living with your cat easier.
All you need is patience and a nail trimmer (either human or pet variety works fine). While your cat is relaxed and sleepy -- after a meal is a great time -- slowly expose a single claw and praise your cat. Over time, let your cat get used to you handling her feet gently as part of a petting session, exposing all her claws without clipping them.
After your cat is comfortable with having her paws handled -- this step can take a few days or more, depending on your cat -- nip off the very tip of a single claw. Don't push: While some cats may not mind a swift progression to having all claws nipped in a single session, others may tolerate only one nail tip a day.
Always end your trimming session with praise and petting, of course!
