Shelly is obsessed with the printer. Of course, his interest draws the attention of Lazlo and Spooky.
But it's gotten so bad that we have to unplug the printer before we go to bed and before we leave the house.
...Because Shelly also likes to shred the paper. So - once he steps on all the buttons and the machine turns on, he steps on the buttons more and paper comes out (the sheet feeder). THEN he gets to grab the paper and shred it!
So plugging and unplugging the printer has become part of our ritual. Just like hiding the paper towels in the microwave, making sure the bathroom door is open enough for cats to get in and out of, etc. etc. etc.
