We received a free PETLIBRO Castle Infinity Cat Tree in exchange for an honest review.
Cat trees are some of the priciest things we buy our cats—but they’re also one of the most critical, since cats need a home that lets them express their natural behaviors for their physical and mental health.
Cat trees encourage cats to explore their three-dimensional worlds, fulfilling their needs to climb, scratch, and hide, explains Stephen Quandt, Feline Training and Behavior Specialist and owner of Stephen Quandt Feline Behavior Associates, LLC.
Cats are also attracted to novelty—”Variety is the spice of life,” Quandt says—which means the best cat tree may be one that you can reconfigure, offering novelty and safe familiarity all in one.
Starting at $199, the PETLIBRO Infinity Cat Tree does just that. It has a unique modular design that lets pet parents easily rearrange the tree into new configurations. We know cats can be picky and buying them furniture is always a gamble, so we put this cat tree to the test.
PETLIBRO Infinity Cat Tree Key Features
Rather than using materials such as MDF-covered carpet, the PETLIBRO Cat Tree is a modular design constructed of plastic, felt, and sisal rope. It features locking mechanisms that snap platforms into place, giving pet parents the creative freedom to build a cat tree that best suits their felines and their space.
Pet parents have three core cat tree options, which can all be mixed and matched to create your own feline abode. Keep in mind that the brand doesn’t recommend the Infinity Cat Tree line for Maine Coon or Serval cat breeds.

The Loft Infinity Cat Tree has a maximum configuration height of 29.1 inches (2.4 feet). It has two felt-covered platforms, four sisal-wrapped scratching posts, one corrugated cardboard scratching board, one plush toy, and a sponge-filled felt bed.
Villa Infinity Cat Tree ($299)
The Villa Infinity Cat Tree has a maximum configuration height of 40.9 inches (3.4 feet). It has three felt-covered platforms, nine sisal-wrapped scratching posts, one corrugated cardboard scratching board, one plush toy, and a sponge-filled felt bed.
Castle Infinity Cat Tree ($399)
The largest of the PETLIBRO Cat Tree options, the Castle Infinity Cat Tree has a maximum configuration height of 58.7 inches (4.9 feet). It has four felt-covered platforms, 13 sisal-wrapped scratching posts, two corrugated cardboard scratching boards (one with a bell ball), two plush toys, and a sponge-filled felt bed.
Currently, there are no options for mix-and-matching accessories or choosing different colors. However, the brand says it has plans to offer more DIY accessories in the future.
Not sure you or your cat will love it? While PETLIBRO offers a 30-day return policy, it only applies to cat trees that are unopened and unused. The brand will not accept a return if the box has been opened. PETLIBRO Cat Trees come with a 12-month warranty.
Testing the Infinity Cat Tree
My 10- and 11-pound cats and I tested the PETLIBRO Infinity Castle Cat Tree for over a month, reconstructing the tree four times.
What we like about the PETLIBRO Infinity Cat Tree:
- Easy to assemble
- Easy to reconfigure
- More affordable than comparable trees
- Easy to care for and clean
What could be better about the PETLIBRO Infinity Cat Tree:
Assembly is straightforward
Like other cat trees, the PETLIBRO Infinity tree comes in a large box that you can either slide across the floor or ask your stronger partner or roommate to carry to the cats’ room. Once it’s laid out, it’s easy to assemble, requiring only the included hex wrench and about 15 minutes. Aside from the base, the pieces are lightweight and either twist into each other or snap into place.
I built our first two configurations by following the manual. We later went off-manual, customizing the tree to better fit our space.
Cat trees can be an expensive gamble. But even as I set up the PETLIBRO tree, my cats were eager to sink their claws into it. They scratched at the posts and batted at the ball-embedded scratcher before I could even put it all together.
A design that’s simple to reassemble
It would be frustrating to dish out the money for a customizable cat tree that’s too time-consuming to bother reassembling. Luckily, we found that’s not the case. Re-arranging from the base up does take a little more time, but swapping a platform here and moving a bed there can be done in a few minutes.
We also see a lot of advantages to the moveable design already in retaining cat interest—and Quandt says the science agrees. He explains that cats are problem-solving hunters. Sure, they’ll probably use the same cat tree for years if they like it. However, providing something new will always spark newfound interest, even when it’s just a platform at a different height.
Plus, as your cat grows out of their kitten stage, into adulthood, and enters their golden years, this cat tree can be adapted to fit their preferences and abilities.
What’s more tempting than just reconfiguring my PETLIBRO Castle Cat Tree is purchasing a second one, since all the parts can be combined to make a cat tree that spans the width of my wall.
A comparatively affordable option
The PETLIBRO Infinity Cat Tree isn’t a budget option—but it’s certainly on the more affordable end of the price range for luxury cat condos.
“Most trees aren’t configurable,” Quandt points out, and he’s exactly right. Basically, there are two modular cat trees designed for reconfiguration: The PETLIBRO Infinity Cat Tree and the Omlet Freestyle Cat Tree, which starts at $196 for a single pole and platform—making the PETLIBRO the more affordable of the two.
Durability isn’t perfect—a part broke in the first week
I don’t have a lot of faith that a plastic part secured to cardboard with glue is going to withstand my cats’ shenanigans. Case in point, the glue used to secure the scratching board to its fastener failed within the first week of use. It’s worth noting that customer service responded quickly to my request for a new scratching board. However, I was told that the part is out of stock.
That said, the plastic platforms and felt inserts show less wear than a traditional tree with carpeting. They’re also easy to wipe clean.
We haven’t had any problems with the snap-in-place mechanisms so far, and I’m optimistic that the tree will last for many years of play.
Comfort is so-so—it’s good for climbing but might not be your cat’s first choice for napping
Let’s be honest, a sponge-filled felt bed doesn’t scream comfortable, and many cat-tree buyers have complained about this. The platforms are made of plastic with a thin felt insert in the middle, and the felt the bed has a sponge-filled base that is only about an inch thick. The bed of the Infinity Castle comes with a hood that is too small for my ten-pound cat to fit inside comfortably.
Is the PETLIBRO Cat Tree Worth It?
A customizable tree is a fun and functional twist on more traditional cat furniture, which is why we think the PETLIBRO cat tree is a strong choice. We only hope that the brand offers customers the ability to purchase add-on or replacement accessories.
Basically, the brand has the opportunity to make this cat tree one that pet parents can use year after year, replacing any parts that begin to show wear or that your finicky feline grows out of. Personally, I love this concept because it allows you to use the tree for much longer and adds new elements to your cat’s environment without alarming them or costing too much money.
