Matt got me a "Pet Series" Roomba vacu-bot for my last birthday. I was mightily pleased, as it does a great job of cutting down on the inevitable cat-fuz tumbleweeds (fuzzleweeds?) that occur when you've got four mainly-indoor felines in residence.
The cats, however, while they don't take off in mortal terror upon hearing the Roomba start up, are...not exactly fond of it. Sometimes Nikki yells at me when it's on in a manner that can only be interpreted as, "TURN THAT THING OFF!" But mostly they all just avoid it. And sometimes they find very creative ways to do so.
Case in point: I often put the dining chairs up on the table in order to make it easier for the Roomba to sweep underneath said table. Last time I did this, I left the room for a moment and came back to find both girlcats had taken full advantage of the situation.
Technically, kitties are NOT allowed on the table. But as they are allowed on the chairs, I figured I couldn't in all fairness shoo them down. So I took a picture instead. :P
