It's amazing how much cats love cardboard. It sometimes seems silly to me to spend money on cardboard, but the right design is so helpful in getting cats to stay off the furniture and in the cardboard home. My cats love their Cat Scratch Lounge and will both sleep in it and scratch it. It has saved the furniture.

I don't know that you can force cats to use it if they don't like it.

My cats favorite spots are on top of the radiators, on the bed with me, under the bed, or a particular chair that is by a large sunny window. I don't know that I could force them into a cardboard box elsewhere

You can never force them, but sometimes the location changes everything. I've brought home things that the cat's showed no interest in, then I'd toss it somewhere out of the way, and all of a sudden it becomes a big hit. You just never know with a cat. However, nothing I've ever brought home compares with a box thrown on the floor waiting to be taken out to the recycling bin. Go figure.

You seriously need to be a paris hilton to make pets wear clothes. They are animals, not toys.

My cats already have a bed: it's a queen-sized bed that's in, what I foolishly call "my", bedroom. They do allow me to sleep in it, which I'm thankful for.

They don't, however, allow me to make the bed, preferring the comforter to be lumped up in a pile instead of lying flat.

$30 for a cardboard box? And it looks pretty small in that picture--that kitten won't fit in there for much longer.

I haven't bothered with cat beds for years; the cats just never seem to like them and the beds take up a lot of space in an apartment.

In this case, I would take a blanket or towel that the cat already recognizes as their own, sprinkle a little cat nip into the folds, and put it in the house. Get the cat into the house (or near it), and they'll be drawn in by the scent of the cat nip. Most likely, they will be attracted to their new "home". I did this recently with a new cat bed that I purchased for my super picky cats. It worked like a charm.

That is cute but I feel like it's so hard to know with animals. I foolishly bought my cat a bed (at least it was on sale) and she won't even go near it, despite many attempts with catnip. And while she does tend to love cardboard (but not for scratching, despite many tries with catnip!), she also chews on it-- rendering it a short-lived delight. Really, the things my cat is most fond of are free or very cheap, e.g. a large, shallow cardboard box in which I cut holes and little doorways. Not only does she love to play mouse through the holes, but she sleeps on top, so now it's sagging and very much an eyesore...but she loves it... (Her other favorite thing is a $3 springy wire with cardboard on it called Cat Dancer.)
Oh and my parents have a golden lab who only humped--never slept on--his bed before destroying the cover completely. He prefers couches and human beds.
