I was thinking I love my cats dearly but if I could change just one thing, what would it be?

Buddy--He is almost a perfect cat all around, however, he claws the furniture and he has all 4 claws.

Mama--Such a sweet girl for the most part but she will swat me for no apparent reason. She can be all lovey and I'm petting her. When I start to walk away...out comes the paw...SWAT!

Tinker--My little love bug, curling up in my lap, however, I would like it if she would not claw the carpet.

Anyone want to share?
