Welcome to Pet talk!
Sorry to hear that sox is not well, but I'm sure with your care a recovery is just around the corner
Both your cats are beautiful, I have two cats, Jack and Sunny who were adopted from Cat's Protection in South Wales. You can see their pictures in my avatar though it's small. They have cat pages on catster if you would like to look (you must get pages for tangerine and sox if you can!) Though catster is down at the moment, I'll post their ID's here later for you to take a look.
That is very interesting that you study martial arts, I also do martial arts, I study Choi Kwang Do, and have done for the past eight years. Which is basically a striking art, no grappling (thankfully! lol)
Hope you and sox get well soon, and recuperate together.
Kate
