I'm in Information Technology and spend approx 12 hours a day on the PC, including the weekends. I can't work from home any longer because of the interruptions. I can get a solid 30min of work done before having a toy dropped in my lap or jumping up for a monitor obstructing headbutt and nuzzle.
If you have an iOS or Android tablet, these are going to be super helpful because keyboard and mice will be walked on all the time. They want to interact with you and if you try to work around them, they will rub on your hands or obstruct your monitor. That's where a second cat or the G/F will enter the mix, they can entertain each other and give you some relief!
At this moment, I have 1/2 a dozen scratches on my right arm and 4 on the left from Isis jumping up with a toy using the arm of the executive leather chair as a spring board from the floor which inadvertently catches my arm along the way. Collateral damage.
