Cedar Cat Trees -- The Outdoor Option That Gets Better With Age
The buyer's spec guide from someone who has tested hundreds of pieces over 40 years.
Most outdoor cat trees look identical in the product photos. They are the same basic shape, the same number of platforms, often the same price range. What the photo does not show is what happens at year three -- which ones are still solid and which ones you are quietly planning to replace before anyone notices.
Why Cedar Gets Better While Everything Else Gets Worse
Most outdoor materials are fighting a losing battle with weather from day one. Painted composites start chalking by the second summer. Synthetic resin coatings fade unevenly and eventually crack at the stress points -- corners, joints, anywhere the material flexes under load. The degradation is slow enough that you rationalize it, until the day the platform gives slightly under your cat and you realize the furniture lost the fight quietly, without announcing it.
Cedar works differently because it is not trying to resist the outdoors -- it is built for it. Eastern White Cedar contains natural oils that actively repel moisture and insects without any surface treatment. As it weathers, it develops a silver-grey patina that looks intentional rather than abandoned -- which is why cedar outdoor furniture from decades ago still holds up. The Outdoor Cedar Cat Gym is the clearest example of this standard in our catalog.
"When I evaluate an outdoor cat tree, the first thing I look at is the post -- not the platform, not the finish. A 4-inch solid cedar post maintains its structural density as the wood dries and seasons outdoors. Anything narrower and you are relying on the hardware to hold the piece together rather than the wood itself. The base is the second check -- width and depth, not just height. A tall structure with a narrow base is an outdoor liability. Every piece I approve for the cedar line shares the same principle: the wood does the structural work."
The Specs That Actually Determine How Long It Lasts
Post diameter is the starting point, but it is not the whole picture. Platform size matters for how the tree gets used -- a platform that is too narrow is one a large cat will avoid, which means the piece stops being furniture and becomes an obstacle. Our cedar perches run 16.5 inches wide and 18 inches deep, which is enough room for a cat to actually turn around and settle rather than perch nervously at the edge.
Assembly is included in the cedar buying experience -- all hardware and a square head screwdriver bit ship with the piece. It is worth taking your time with it: a cedar tree assembled carefully, with every joint fully seated, will be solid for years. One assembled in a hurry will have a wobble that has nothing to do with the material. If you are comparing options, the Outdoor Cedar Cat Tree and the Indoor/Outdoor Cedar Cat Gym Small are both built to the same standard at different scales.
The post connection and hardware quality are what determine whether a cedar tree holds up at year five -- not the finish.
One More Thing Worth Knowing Before You Buy
Cedar cat trees ship unfinished, and that is intentional. Left natural, the wood weathers to a light grey patina that most cat owners find looks better than the original -- earned rather than applied. If you prefer a specific color or want to protect the wood's natural tone, the surface takes stain, paint, or sealant cleanly.
"The question I get most often about cedar is whether it needs to be sealed before going outside. The answer is no -- and that is actually one of the things that makes it worth carrying. You assemble it, put it outside, and that is the end of the maintenance conversation. The cedar line also comes with sleeper platform and roof add-ons if you want more configuration. It is the kind of flexibility that makes sense once you have committed to a material that is going to be in your garden for a long time."
