Funny how they do that. Our cat was the same - she'd been in the apartment for perhaps a week, and when we finally gave her run of the full apartment, we were really happy when she jumped up on the bed to be with us that first night. She was initially skittish and I was surprised she was already willing to approach us. Until I realized she'd carried a roach with her! (A gift for the two people who had suddenly taken her in and started to give her food?)
I mean, I know the roaches are around, but we've now had two cats for over ten years, and in that time they've found and killed maybe six or seven cockroaches in total - it still seems weird that she caught one her first night on the loose, and approximately one every two years ever since. But I guess the presence of the cats keeps the roaches under control? Or, and god I hope not, they're eating other cockroaches and so I never see the corpses? Or one day I'll discover a little hidey-hole, and they've plonked dozens of corpses in it?
Meanwhile one of my cats has decided he wants to play, so he's gone into the other room, started to miao plaintively, and begun knocking things off the shelves. Sigh. Duty calls.
