You need to install one or more cat containment units. Our favorites are the 9x11 inch, soft grey boxes with 4 inch flexible sides. (Cardboard boxes also work, but my managers prefer the soft and flexible feel of the store bought merch).

The delicate cat diplomatic situation in my office meant that I could only use two traps at once, but it looks like you could manage three without any additional treat-ies in place.

They fit, they sit, and they quickly fall asleep. No more keyboard interference. No more reminders that it's only 3 hours until feeding time. No more worrying about whether you need to report them to HR when they demand you "touch my butt now."
