suitable for small cats
582661
This is a basic, simple, small cat tree.  The size makes it unsuitable for large cats (the curl-up top area is about 11 inches across).  I think our cat prefers to be a little bit higher/out of the reach of dogs.  Those who don't have these two issues may find that AmaxonBasics meets their needs.

I had some trouble with this when I first bought it. I have a rather large and clumsy cat who became more reluctant to use it over time as the opening is somewhat small. I cleaned it, put it away and got something more suitable for him. I gave this to my parents when they had a need and it is perfect for their petite cat. A good product, though not for everyone.

I like it in that it was easy to put together.  I, however, failed to really consider the measurements.  So make sure you really look at the size of it.  I have two big cats that look ridiculous next to it.  However, for the the small cat this is the perfect size.  So it's basically all hers. It fits nicely in the corner and gives her a great view out the window.  One of the big cats does take to using it as a step to get onto the window ledge.  So it has it's uses.  Plus the scratch posts at the bottom, total furniture saver.

Two cats have used it for 1 month, no real signs of wear. It is made with similar quality as a smaller unit I purchased at Petco.

I have two cats over 15 lbs. The cat tree seems a little small for them but overall good enough. Reminder, It is not stable enough for fat kitties! It shakes! I mean I can see it is shaking when my cats are playing it.

It is small, and I have 2 cats, one very small and another very big , but both of them like to use this , although they have a big litter box as well

Easy enough to put together and shipped on time. It's smaller then it appears. And I've big cats. They did not fit on this at all. And a it's a bit flimsy in the build up top so I wouldn't trust it to a heavy cat. I gave it to my mom, her cat is small. If you've small kitties this is for you.

I am very pleased with the cat tree overall, however my only issue with it might be the fact that it is a bit small for my adult male cat. The assembly process was very simple which I appreciate. He likes being up on the third tier, but I have yet to see him utilize the scratching posts. In the future I will probably search for something bigger. I imagine this tree was meant for kittens and petite cats.

My cats like this a lot. It doesn't get super hot, but it's warm and gives them a nice thing to lay their heads on. It's definitely too small for both cats to fit, and for small cats one is already snug. It does the trick though.

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

This is a great little convertible bed/house for a small dog or an average cat. There are two parts: a cushion, and a base. Either the base is folded in on itself to make a traditional four-lipped pet bed, with the cushion placed inside, or the entire top is extended to make a house with a circular hole in the front, with the cushion placed inside, and it looks like a standard cat hidey-hole.

It looks tasteful enough, certainly by pet furniture standards: brown with a brown and white check pattern on top. Our largest cat can just get in there; it is of course, somewhat flexible due to entirely being made of fabric. Your dog would need to be tiny, however. I've seen Westies that would be too big for this.

As the final seal of approval, one of our cats has claimed it as exclusively hers.

quite nice little lounger.  It is a little bit wobbly when my big cat jumps but other than that, they love it, especially the scratching side.  price was reasonable, too.

The urban bench style scratcher is sturdy enough for my 10-12lb kitties.  It looks just like the picture.  I like the styling of the scratcher.  The issue I've seen is that my kitties end up with their weight on the ends of the bench and it tips over.  It is not their favorite scratcher for that reason, but they still use it from time to time.  I will likely look for a more stable scratcher the next time I buy.

Good for a smaller scratching post.  Does not tip over.  Flat on top so kittens can sit on the top.  Nice quality/

Nice small morsels for smaller cats.  I got the runt of the litter and love that she will not be very big.

Was a little small for my cats but they still love to play on/in it.  Great for smaller cats. Decent quality.

Nice litter pan, easy to clean. Small, so good for smaller cats. I use mine for my rabbits. Glossy finish is good for wiping clean.
