Late one evening, about 15 years ago, we were wondering why we were seeing several hits per second from a single IP address on our company's search page. It didn't follow any of the patterns of the (admittedly simple) bot detection we had in place. It wasn't bad enough to be a problem, but we were trying to watch some real-time metrics and it was a distraction.

We had a monitor on the wall showing the most popular search terms over the past hour. A few minutes into the event, we saw a search term steadily move to the top of the list. It was something like `'[]`. After thinking about it for a few minutes, we concluded a user left their browser on our search page, a cat stepped on their keyboard in just the right pattern, and then sat down on the F5-key (i.e., refresh key).

No way to know if we got it right, but it was the best we came up with in the 20-ish minutes before it stopped. Oh the things you'll diagnose...

Some internal Skype versions had cat detection. When the client discovered cat-like key presses, the other side would see a cat walking animation instead of typing animation. Don’t think this feature ever made it to a public release.

And they might turn you into the Freakazoid

Oh, I really believed this was some strange keylogger spyware. Maybe it is? I really can't tell. Either this was the hook to get people to install it, or the front to make it seem like a real thing when people find it and google "why is pawsense installed on my computer".

> Even while you use your other software, PawSense constantly monitors keyboard activity. PawSense analyzes keypress timings and combinations to distinguish cat typing from human typing.

On an OS like Windows, which does not have a granular permissions model for something like prompting the user to allow a program to hook keyboard input when not focused, literally any binary you run could be a keylogger. One that openly says it analyzes keypresses is not especially more of a security risk than any other binary, which can do all the same things even if they do not announce on their webpage that they do.

> Except when playing a sound (when a cat is detected) PawSense occupies less than 120K of RAM.

Maybe add a 1999 or 2000 datestamp to this (it won the https://en.wikipedia.org/wiki/List_of_Ig_Nobel_Prize_winners... Ig Nobel prize in Computer Science in 2000...)

I give it One Star: It keeps locking me out of my computer whenever I rage at video games, which makes me rage further.

This is timely. Out of my five cats, my primary boy has been really needy or making a game out of hop on table, walk on keyboards, get picked up, scritched and tossed down. Repeat. Even cat tv on youtube hasn't been helping.

Unfortunately the program can be bypassed by typing “human”

Ultimately all this does is incentivize cats to type more accurately when inputting malicious commands

Aluminium foil on flat surfaces works very well.

After the cat has been trained to avoid the shelf or desk, you can remove the foil.

Highly hit or miss strategy, my cat didn't care at all about foil, he even rolled around on it.

I personally recommend motion-detecting air spray cans, I didn't want the cat to feel punished by me, he just needs to be redirected. Therefore I opt for these as a deterrent, since it is both effective and an action I undertake from the cat's view. I think he hates it because of the hiss, but the air spray itself might play a role.
