Not a joke: buy a cheap pair of padded overalls - the sort that are quilted for cooler temperatures. You should be able to get a pair for $40 or so online. That's a LOT less than the cost of cat scratch fever. You'll be almost Kitty Proof while you're wearing them.
To some degree, if you've got cats, you just sorta get used to the scratches and cuts after awhile.
I had cats once, 4 of them. One of them was a bit overweight, and she'd frequently try to jump up on my lap while I was at the computer. Sometimes this was fine. Othertimes, she would miss. And that's when the claws come out and the wild flailing begins.
It's as much fun as it sounds like it is.
