Modular Cat Tree by Katris – Have Fun with Building Blocks


I will start by saying that I love modern cat furniture. The days of boring plain cat trees covered in carpet are past and nowadays manufacturers are becoming more creative in their designs. The modular cat tree by Katris is definitely cool looking and fun as well as being great for cats which is very important.

This Katris tree is basically tetris for cats. Just look at the photos and tell me that that is not the first thought that comes to mind. Β This cat tree is a set of blocks that you can fit together however you want to make different designs.

You do not even have to place all the blocks together to form one tree. In fact you can set them up as two or three different shapes. You can even fit some to the wall. And you do not have to make the tree 2 dimensional. If you place the blocks in different configurations you can make a 3 dimensional tree. You can basically let your imagination run wild.

Not only that, but this piece of furniture is not only for your cats. You can place books or other items inside the blocks. Just be aware though that if you place breakable items in the block your cat might just think they look better on the floor.

Whats in the Box

You can buy the Katris modular blocks either as a set of five blocks or as individual blocks. Buying the individual blocks means that you only buy the ones that you want. So if you want a square shaped block to hang on the wall then just buy that item.

You also get 10 clips to hold the blocks together, 5 bags of catnip, 5 matching covers in your selected color and 10 cat toys.

The Katris modular cat tree also comes in a variety of different colours:

  • Black
  • White
  • Original Kraft
  • Maple
  • Multi-color
  • Teak

And you can mix and match your sets. Buy a black set and a white set and make a large black and white cat tree. Or convert part of the tree to a bookcase. This cat tree is definitely only limited by your imagination.

What Are the Parts Made From

But this is not like a flimsy cardboard box – it is designed to hold up to 300 lbs in weight. So will be able to take books and even the largest and fattest cat.

The cardboard is also non-toxic and designed to be scratched. All the blocks are different sizes and dimensions but they each weigh between 8-9 pounds.

The sizing ranges from 16 inches by 8 by 16 inches to 24 x 8 x 16 inches to 32 x 8 x 8 inches depending on the actual block shape.

  1. Awesome info for cat lovers! the blocks looks very nice and such a fun and creative ideas, the cats will love it a lot! and it look not just a block for cat but also a cool stuffs to the home decoration!
    Thanks for sharing it πŸ™‚

  2. This is a cool idea!
    I used to have a cat and I wanted the more fun “cat accessories” rather than the cat towers and things that everyone seems to own. I think one aspect that I like about these too is that they do not look like a crazy cat lady lives in the home because the blocks look multipurpose (decoration and cat uses).
    They add a nice touch to the home and then are adorable to see cats running around on them πŸ™‚
    I am glad I know about these now – once we move into a home from our apartment, I will want cats again and these are what I am coming for!


  3. Oh awesome, I love cats (big cats are better, lol) so this should come as no surprise that I might have to get one of these for my cats. Anyway, I really like how they are on Amazon, as I shop there often.

    I’m going to send this page to my partner right now and see what she has to say about it, she’s a big cat lover as well πŸ™‚

    I don’t really mind that they are expensive for a set either, what do you expect for a high quality material for your furry friends that you love so much? Haha

    Thank you for this great article.

    1. oh yes I love big cats too. Probably why I like Ragdolls. And yes I think I buy more furniture for my cats than for me — but at least with these I can also use them

  4. Very interesting. Not sure if I could use it though. I did just adopt a cat that was abandoned when a neighbor moved out but she’s been de-clawed. She likes to jump up on my desk and get between me and the computer screen. Sometimes she puts her paws on my keyboard, which can cause problems. But she doesn’t seem to want to climb around much. Mostly just wants to be right where I am.

    1. Really sorry to hear that she has been declawed. Sadly that is one of the issues with declawed cats that they have problems jumping and climbing. Glad to hear that you adopted her and hope that you and her enjoy each others company

  5. Hi Evie, I love the look of these. The fact that you can use them however you want and build a play tower how you want it to be is pretty unique. At least it’s not something I’ve ever seen before as cat towers are usually what you see is what you get construction wise. These must be pretty heavy blocks otherwise the cats would just knock them over.

    1. Thats why I love stuff like this. I got bored with the old type of cat tree which was just covered in carpet and looked untidy after a couple of weeks of use. These can be used in the lounge or anywhere and look great for you and your cat will love them. They are about 8lbs each in weight so not too heavy. A full set though when delivered will be pretty heavy in the box
