Cats are all individuals and some felines may create havoc with humans engaged in radio hobbies. I had one cat many years ago that enjoyed chewing on rubber duck antennas attached to radios. He never damaged the radios or the antennas to the point where the antennas became non-functional. My current feline does not chew on anything but food, does not intentionally knock over radios or play with coax in any way shape or form. Most of my antennas are outdoors but a few are indoors, suspended from the ceiling so my cat will never get to them. If I say to my feline companion, in a loud and commanding voice, "no", he will not engage in the act that I forbid him to do. Personally, if I had to choose between having all the radios that I wanted or having only cats with no radios, I would elect to possessing cats as they provide company and companionship that radios cannot provide. I don't believe that I will ever be in the position of having to make a choice like this. Cats and radios will be with me until the day I die. The below photos were taken in my Winter radio room, a space that is easy and cheap to heat.
