Is the Renwick 54 stable enough for a large cat?

A tall tree carries more leverage, so a heavy or very active cat can make it sway. Place it against a wall or in a corner and check the base is fully tightened after assembly.

How is it different from a smaller cat tree?

It adds more levels and resting spots, so cats get more climbing and perching room. The cost is a larger footprint and more assembly than a compact single-perch tree.

Does it work for more than one cat?

The multiple levels and hideaway give cats separate spots, which helps in multi-cat homes. Very dominant cats may still compete for the top perch.

What do I need to assemble it?

Expect to attach posts, platforms and the hideaway with the included hardware. A screwdriver and a second person help with the taller sections.

Where should I put it?

Put it in a corner or against a wall for extra stability, near where your cat already scratches. Keep it off high-traffic paths so it does not get bumped.
