"Cat towers"

I snapped this pic this morning as part of my (winter) morning routine. The routine involves sending the cats outside for the day. In the winter they don't always want to go. Harley, the black and white one, hisses and tries to bite me. She's gotten better about the biting, but she'll still express her displeasure by hissing. Even when she's in that little bed of hers. When she's there, in the "cat towers", I just grab the whole thing and she gets a "magic carpet ride" to the door. I sometimes sing "Up, up, and away, on a magic carpet ride". Sidney, the grey one, clues in as to what's going on and she jumps down and runs under the bed. I then have to employ the "angry cat mom" technique of grabbing her by the scruff of her neck to pull her out. Funny thing that—I guess they retain this from kittenhood, but they still appear to respond the same way as when mama cat would grab them this way: they kind of go limp. Sidney even curls her tail under. When the weather gets warmer, both cats look forward to the outdoors, so in a matter of weeks I think some of this behavior will subside and in fact they'll start meowing to be let out.
