I mistreated a cat
Why would you mistreat your cat?
I wanted to stop it from scratching my arm
It's terrible to mistreat animals. You should learn to show some respect to them.
I just wanted to not get damaged with its nails. I thought it was not a big deal.
It is a big deal when you hurt animals. If you don't want the cat to hurt you with it's nails then you should cut them short.
