Hi,
My cats did quite a few things. First, this is mostly non-tech related though.
So, I was tired, and wanted to go to sleep. It was about 5 AM. I wanted to lower the blinds, but somehow ripped them off the handle. Completely. So, crash, boom, they came crashing down on me, everyone probably awoke.
I temporarily put them back up, telling myself "I'll fix it later". Of course, as it happens, I totally forgot.
So, next day passes, nothing interesting happens. Then, it was night. Around 2 or 3 AM.
I think I was coding at the time. Suddenly, I hear this very, very loud noise from the other room. I jumped up, dropped the headphones, and ran over to discover that... My cats totally screwed up my temporary fix for the blinds, making them fall a second time. It wouldn't have been so bad if the house wasn't totally quiet, and it was 3 AM.
Another time I was composing an orchestral, sorta scary themed track. I don't remember what it was for, but I was doing it. So there comes my cat, jumps onto a table next to my keyboard, and randomly presses 2 keys with her paw. She didn't climb on top of the keyboard, she just pressed the keys, like she knew what she was doing.
The thing is she really seemed to, as the 2 notes totally fit, and I left them in! I'd show you, if I can find the thing again.
Another time, while I was playing Bokurano Daiboukenn 2, my cat saved my life by most likely accidentally pressing up arrow, then promptly stepped on the space bar. Who knows, I might have had to do the level again, thanks to her. But luckily she stepped on C too, meaning she paused before she could screw it up again.
Also, my cats seem to prefer my window as the means of getting into the house. Which is totally weird, since my window is on the first floor, and she could actually just walk in the door on the ground floor. But no! She stands there, meowing so I would open the damn window first.
However, my cats have also contributed to some loss of code, bleeding wrists and scratches, but it doesn't matter. They're so cute!
