Euthanasia.

The whole time I thought you were talking about your wife until the very end. You should write a book.

I automatically hate any FML that tries to disguise its subject until the end.

Cats become aggressive for a reason. You need to find out why. She might be redirecting her aggression to you if feral cats are outside. She can smell/hear them and then attacks you. Or she may need more stimulation.

Haha at first i thought she was your girlfriend or wife till i saw the word cat I'd say buy a scratching pole or something?? That way her claws would be busy scratching something else and won't be as sharp??

You do realize that you are a human right? Your size gives you the ability to stomp its guts out. There will be a mess, but since you have thumbs it.won't be hard to clean up.

Declaw it?

Here we go Step 1: find a trash bag Step 2: find the cat Step 3: put said cat in bag Step 4: throw bag at stranger while running and yelling its yours now

Shelter

Is this how your cat plays? Or is it just an asshole? I know some animals play really rough. My Australian Cattle Dog would run at you full speed and tackle you...and keep running Circles around you, as you gasp for breath.
