At work when I went out to put the food out for the ferals, little Roomba was in his usual hiding place in the bushes. As soon as I came through the door starting my meow-talk to him and of course he answered. To my shock, he actually came out of the bushes and was rubbing on the dirt and the branches for a few seconds then went back into the safety of the bushes. Maybe after all these months, I'll finally be able to get him to come to me so I'll actually be able to pet him! How exciting! Made my day!
