Keeping cat away from monitor: Localized ultrasonic 'no-cat' zone..
Hi,
Here's an idea I've come up with in the past few weeks: make a device that would create a focused, low-intensity ultrasonic field that could create (hopefully) a "no-cat" zone in front of a computer-monitor for instance (this is our problem) The only two problems I see is 1) making the signal low-level enough that it would just annoy the cat a little and nothing more, and 2) figuring out how to focus it. I'm thinking pizoelectric speakers might be able to do that. What is the an *upper* limit on what cats can hear? The "focusable speakers" that I've heard of work by using two ultrasonic signals to create interferance patterns low enough that people can here them (cats could be a problem here). Theoretically, the same could be done for cats, except that the source frequency would have to be higher than the upper range of the cat's hearing. Other than that (which would take quite a bit of stuff, time, money, math, and experimentation to make), does anyone have any idea how to teach a cat not to walk back and forth in front of a computer monitor. Other than having the owner pet the cat rather than use the computer - which is of course what the cat wants, althogh I think our's does it just for spite. We would be perfectly happy if he'd just either sit off to the side, or lay down, and we'd hapily scratch his head. But no - he insists on wandering back and forth in front of the monitor, and unfortunately, none of us have X-ray vision and the cat is not transparent Jim |

does anyone have any idea how to
teach a cat not to walk back and forth in front of a computer monitor. You could use a "scat mat." I personally let me cat sit next to the monitor on her own mat. She will walk in front of the monitor when it's dinner time, then I feed her. |

Well, I had a similar problem. One of my cats seemed very jealous of the monitor because it got so much attention from me that one day he simply peed on it - this was about a month ago. Oh well, the monitor burned, obviously, and couldn´t be fixed. I got another monitor and made a wooden box to fit it inside leaving 4 inches on each side and six inches on the top to avoid overheating. My cats used to love sleeping on top of my old monitor too and that problem is also gone with the box. You can make the box deep enough to reach the edge of your table so that way the cat will not be able to keep crossing back and forth in front of it. Wish you luck and hopefully your kitty won´t pee on your monitor. |
