Well, at least the cats seem to like it.

I got this for my adored one, Sarah, a Cavalier King Charles Spaniel mix, who, despite her royal name, insists on sleeping on the floor, much to my distress.  It's part of an ongoing quest to find a dog bed she'll actually use.  This is not the bed for her, she has ignored it, not even so much a sniff of passing interest.  But that's not why I gave a mere three stars.  After all, just because my particular, picky princess turns up her muzzle at this bed, doesn't mean it's a poor product.

No, I gave it three stars because it took three people and the strength of Hercules to put the bloody thing together.  And after we did get it assembled, it was warped.  The warping has settled down over the past few days as my cats have played on it and laid on it, but it was quite disconcerting at first.

And what a time they have had!  They play king of the castle on it, they sleep on it, they bat at one another through the holes in the corners.  It has been a huge hit with my young felines.  That is the only thing that kept it from being sent back.

Meanwhile, the quest for a Sarah-acceptable dog bed continues...

The cats seem to like it.  The hair balls still occur once in a while.  Need to give it more time to see what happens when the cats shed in the Spring.

My cats are pretty happy with it.  Some spots in it are hard to clean, even with the special cleaning kit, but managing.

My cats like it but are not crazy over it like some other products. Still they did eat it.

The scratcher looks about as good as a cat scratcher can be expected to look.  It's larger than I expected, so it didn't fit in the area I had planned for it, but it looks nice enough that I was able to find another area where it didn't look out of place.

It seems durable so far (about three weeks of use).  The cardboard is dense and firm and only showing minimal wear.

The cats like it, and take turns on it even though it's big enough and strong enough for more than one cat.  For the first day or so, they didn't know what to make of it, and I had to cover it with a more familiar cat-scratching pad.  After that they took right to it.

It does look good, but that's only one consideration.  With the price of the item, it needs to last a long time to justify itself.  This was a cat Christmas present, and it's mid-January now; if it degrades faster than expected, I'll update the score.

These seem to be fine -- They seems to be a bit lighter than the original ones I had from another company but if they do the job [and, they seem to be doing it nicely] the kitties are happy and so am I.

It's not so much what I think, but whether the birds like it and they seem to like this a lot.

So far so good, the cats are using it so I guess that a success. It does track a good bit though.

Cats seem to like it. It's a little hard to find somewhere it doesn't look completely awkward though.

Not much to say except that these are our cats' favorites. While they all have particular tastes, they all seem to agree that these are worth chasing - just our way of giving them a little indoor exercise chasing them.

My cats like this so it isn't a problem to get them to eat it.

So far we like this product.  We notice that the cats want feed a little more often, but they like the food.  We switched from Orijen.

Cats seem to like it. Our one cat that had an issue with pancreatitis is OK with this so far. We feed a mixture of this and wet food.

My cats like this and I don't know if it is a good thing or bad, but my adult cat likes it, too. My kitten is thriving and that's what matters.

So far, so good. Both my cats seemed a little wary of it at first, but I turned the fountain down to 'low' and now they're OK with it.  Doesn't make too much noise, but we keep it in the laundry room, so noise is not a big concern.

I like how easy it is to clean and the cats seem to enjoy the texture of the brush.

I can't really give this five stars, as I've not tried these yet, but my cat seems five-star-satisfied, so there you go.
