However, what concerns me is that the last two have been *inside* the house, and I don't think they are catches that he's brought in and let loose for Circe to practice on. The other night, I was sitting on the couch, with Ming asleep beside me, and he suddenly sits bolt upright, listening. Then he becomes VERY interested in something behind the bookcase. After ten minutes of stalking, he grabs something, and I realize it's a half-grown RAT. He growls at Circe, who comes to check it out. I open the front door, and he takes it outside, to dispatch it at leisure. The next morning, I confirm from the remains that it was indeed a rat. Then, last night, Hobbes nails something in the back hallway. It's a mouse. However, he lets it get away, and it heads for cover. I was rather amused at looking around as the cats and I were playing "catch the mouse" to find Ming and I were taking the active roll, with Hobbes and Circe covering the escapes, like some odd team sport. I moved some stuff, Ming chased it, and I did the final catch (by the tail) and chucked the mouse out the back door. Teamwork, I like that.
My theory is that they're getting in via the screen room, since passthrough is still open to give Circe access to her favorite yard-watching spot (but not for long!). And of course, inside the house are wonderful things like munchy catfood, the rodents not realizing that you are what you eat!
