I have five cats/kittens, and finding a cat tree that can withstand their constant climbing, jumping, and scratching is no easy task—but this one has been absolutely amazing!? Extremely Sturdy & Well-BuiltThis cat tree is solid and stable, even with multiple cats using it at the same time. I was worried about wobbling, but it holds up perfectly, even when my most energetic kittens are racing up and down. The base is wide and heavy enough to prevent tipping, which is a huge plus!? Comfortable & Spacious for Multiple CatsWith multiple platforms, cozy hideouts, and plenty of room, all five of my cats can find a spot to lounge or play without fighting over space. The perches are large enough for my bigger cats to stretch out comfortably, and the cubbies are the perfect size for my kittens to snuggle up in.? Durable & Scratch-ResistantThe sisal-wrapped scratching posts are holding up incredibly well, even with daily use. My cats prefer scratching this over my furniture, which is a lifesaver! The fabric is also soft yet durable, showing no signs of wear despite months of constant use.? Easy to AssembleAssembly was straightforward and took me about 30 minutes. The instructions were clear, and all the pieces fit together perfectly.
