How to Assemble a Multi-Level Cat Tree So It Stays Sturdy
Your new cat tree arrived as a box of poles, platforms, and a bag of bolts, and a tall tower that wobbles or leans is one a cat won't trust or use. Proper assembly is all about a tight, stable structure.
Tall cat trees stack carpeted platforms on threaded posts, and the whole tower is only as stable as its base and the tightness of every connection. Bolts that feel snug during assembly often loosen as the cat jumps on and off, and an undersized or uneven base lets the top sway. Good assembly means building in the right order, fully tightening each level, and confirming the finished tower is steady enough that a cat will actually climb to the top perch.
How the job is done
- 1
Sort the parts and read the sequence
Posts, platforms, and hardware are laid out and matched to the instructions, since these towers must be built bottom to top in a specific order to align.
- 2
Build a solid base first
The base board is assembled and its bolts drawn fully tight, because every level above relies on this foundation to keep the tower from leaning.
- 3
Stack and bolt each level
Posts and platforms are added one tier at a time, with each threaded bolt tightened firmly so the connections do not work loose under a jumping cat.
- 4
Attach perches, hammocks, and toys
Top perches, cubbies, and dangling toys are secured last, with hanging toys checked so there are no loose strings or small parts a cat could swallow.
- 5
Test for wobble and stabilize
The finished tower is rocked by hand to check for sway, and a tall unit is anchored to a wall or repositioned against one so it cannot tip when a cat leaps onto the highest perch.
What a pro checks
- Builds strictly bottom to top so platform holes line up as the tower rises
- Fully tightens every bolt, since cat use loosens connections over time
- Checks that the base is wide and level enough to support the full height
- Inspects hanging toys for loose strings or small parts that pose a swallowing risk
- Recommends wall-anchoring very tall towers so an active cat cannot tip them
- Verifies carpet staples and edges are flush so paws are not snagged

Frequently asked questions
Why does my cat tree wobble even after I assembled it?
Usually the bolts are not fully tightened or were tightened out of order, leaving the levels misaligned. Tall towers also need a wide base; if it is narrow, anchoring the top to a wall is the surest fix.
Do tall cat trees need to be anchored to the wall?
It is strongly recommended for tall units. An active cat leaping onto the top perch generates real sideways force, and a wall anchor keeps the tower from tipping over.
The bolts loosened after a few weeks. Is that normal?
Yes. Repeated jumping vibrates threaded connections loose over time. Rechecking and snugging the bolts periodically keeps the tower stable and is part of normal upkeep.
