Cats and tubes

I have four cats, ranging from 20 years (!) down to 2 1/2. Although they sometimes get disconcertingly close to my tube gear, they have never done it any harm. The bigger problem is that they like to jump on my worktable while I'm soldering, but again they've never injured me or themselves. I think they have a very good sense of what's dangerous.
