Have a cat that won't stay off your counters? I do. I finally got fed up with it enough to do something about it: scare the crap out of him with a motion-detecting blender (while recording the results for my own amusement, of course).

Confused at what you're looking at? This is a repeating shot of security camera footage of my cat jumping on the counter - in search of a plant to munch on - and initiating my Blender Defender. Take a look at the following comic (Courtesy of Sarah) to get a better understanding :)

Sorry, but you're going to have to pretend you can hear an extremely loud blender while you watch these clips

Details

If you were to walk in my house, you may see something you dont normally see in a kitchen. On the wall, to the left of my sink is a webcam (network camera). It is plugged into the network jack and screwed into the wall plate cover, supporting itself. It doesnt get it the way, nor do we ever have to think about it. The camera is being monitored for motion by my computer upstairs in our office.

The camera itself is one of the cheapest network cameras out there, the DCS-900. It can be picked up for about $120 or so. There are a couple network cameras that are a little cheaper, but the D-Link one is pretty rugged and makes it easy to get into the raw feeds, something that cant be said for many other cameras.

As you can see from the videos above, the blender and the strobe light are both controlled by an X10 unit. The unit is sent an on or off command from the computer running upstairs by means of an X10 Firecracker. The Firecracker is just a wireless X10 transmitter that plugs into your serial port. I wont get into explaining it much here, but one thing to note is that is happily co-exists with my CM11A unit.

The computer upstairs is running the 'motion' library for linux. As soon as it detects something moving on camera, it starts recording frames. While it is saving frames, it also initiates another Perl script I wrote that sends an X10 command to turn on the blender and strobe, wait 3 seconds, then turn them off. After the script is done detecting motion, it then splices all the JPG frames together using ffmpeg and saves the resulting movie as a SWF file, which you can see above. Finally, after it saves the movie, I have it set up to email me a link to the movie so I can see the results from where ever I'm at (remotely by using my phone).

Is this cruel?

Of course not! To teach a cat not to do something, it has to get the idea that what it is doing is a bad thing. One way to do so is to sternly tell your cat 'NO' when it does something. The cat may learn that it is bad, but more often than not, the cat learns that it's not supposed to it when your around. This is not what you want. The best way to teach the cat not to get on a counter is to take yourself out of the picture. If the cat jumps up on the counter and is greeted with a scare, it will learn that the counter is not a very nice place to be. The cat is never harmed, but it's instincts tell is that this may be something to be feared. Just like a vaccuum. The cat doesn't like it at all, so it stays away.

Some will say that the cat is trying to eat the plant because he needs it for his digestion. In this case, it's just not true. Our cat doesn't simply eat our plants. He sees them as a toy. He plays with the stalks, digs them out, etc. We find leaves in the other rooms half the time. And, yes, he does get grass every once in a while.

Project Cost

The table below shows how much money would normally go into a project like this. This isn't to say that I've spent this much, as I already had everything lying around the place, but if somebody else were to start this project, this may be what they should expect to pay.

The last video is fu***ng GREAT...
Our cat taught itself not to walk on our counters. One day I heard a lot of meowing and jumping around and found the cat on his back licking his paws and spitting like a machine gun. Then I realizes she had walked across our glass top range after the wife had cooked dinner. I could see little paw prints on the glass. She was ok but she NEVER climbed up there again.

So the readers are going to be surprised to find a problem late at night. You get up, go for a glass of water, and suddenly you are looking for the paper towels so you can start cleaning your own feces off the floor. Then *you* are being conditioned ... to approach your kitchen with apprehension, for fear that you'll accidentally set it off again.

The item you are actually looking for is called "Sticky Tape(tm)". (Seriously, that's the name brand I've used). You put it on the edges of the counter. It sticks to their paws and really annoys the crap out of the cat. You leave it up for a couple of weeks, eventually the cat just gives up trying. Cat never returns to the counter again. Then you take the tape off while the cat isn't nearby. Now your kitchen is totally normal, and your counter is cat-free.

Cost: About $15.

Not as awesome looking in action, but also won't may you wet yourself when you accidentally trigger it. There's something to be said about a training device that doesn't give the owner a heart attack.
Mind posting the code for the Perl script?

Okay, one : Yes it was found to be quite humerous. (Send that to A.F.V) and Two: before you declare this as a cruel manner in which to teach a cat or any animal for that matter you need to put into mind that a home is shared by both parties and therefore rules should be set. He does not beat , torture, or throw his animal aside as many frustrated owners may commonly do with their pets. He only did it perhaps once or twice to get the point across. Cat's will most definitly land on their feet and he did this without considering the fact that the cat may have stayed on the counter and let out his nature when it was scared. Also, I am a deep animal activist, having been bitten by animals I attempt to protect and beat by those who wish to harm them. What this man has done is a very logical approach to a matter that could turn sickly for the entire houshold. By observing this man's kitchen alone it is believed he would like to keep it clean and a cat comming in from the elements and climbing upon a counter where thirty minutes later he makes his sandwich is not healthy at all.I do not say this without knowledge as well, cats have strong hearts, and as they grow they attempt dangerous things as training toward life. Sure that may have startled the cat but it did no real harm to either it's heart nor it's stimulus. B.T.W cats are smart enough to be able to give the cold shoulder to whoever did play a prank on it.

Thanks for going ahead and providing instructions for the building device ! While it seems to stir a lot of controversy on the subject of how best to discipline and animal without crossing the line into abuse, I'd like everyone to keep in mind that the inventor of the device is quite ingenious in his use of both light and sound.

We have had a similar problem, with our two cats who seem to always jump up on our counter and get into the bread box ( though we have tried shutting it in a myriad of ways). OUR solution was to get both cats together and rape one in front of the other, afterward punching it in the face all while the other cat watches in horror. For us, this seems to have solved the problem completely.

I am wondering if this really works if you have a place that you post new videos....are you constantly changing cats or are the same cats just not learning to stay off of the counter?
cats are dumb
Wish I had one. The spray water bottle just isn't getting thru to my cats! I thought it was ingenious and hysterical and I own three cats. It's just conditioning.

May I be the first to say that, vajorie, you have no idea what you're talking about. The cat won't hate the OP, nor will the cat even know the OP set it up. The cat has no idea what a blender is or that it was rigged to scare it. All it knows is that it was jumping up on the counter and a loud noise went off. And then it stopped when it ran away. Wash, rinse, repeat. Classical conditioning at it's finest.

And your comment that one needs to setup their house for their pet? So, you own cats? Is your house one big sandbox then? You have vermin running around for it to chase? Sounds like you should be evicted Yes, a ridiculous comment to counter your equally ridiculous one.

"what you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul."

You people that think this is cruel obviously have never been tormented by a disobedient animal. Or you don't mind being submissive to one. Either way, you're retarded and Plasma2002 is awesome.
Haha, this is awesome! Keep up the good work!! Thanks for the notes on how to do it in linux too, sounds pretty easy : ).
vajorie
you're gonna make the cat break a few of her bones in one of those panic attacks, or hit her head and risk epilepsy, or just hate your guts (and rightly so) because, instead of putting the plant elsewhere (or finding out what she wants on that counter), you prefer to torture the cat to no end with stimuli that she has no way of understanding. Having a pet requires *you* to set up the home *for* the *pet*.

We used to tie our cat's tail to the lawn-mower spark-plug wire. One good pull of the rope and you wouldn't believe how high a kitteh can jump! BTW: You all are morons.
Scuzzboots
will it work on ceiling cat? i can't get him to leave me alone at night when i'm having my "me time"
HarrisonFordette
All you bleeding hearts need grab a tighter grip on reality. The whole point of having a pet is to torture it.
Simply hilarious!
Really Marty? You had the vet make your cat sound nice?
gabriel
hey Nugget Hole, your cat just wants clean/fresh running water. he would stop doing that if you changed his water dish EVERY DAY or 2x a day, or bought him a water fountain. idiot
