Is this cat tree stable enough for large cats?

It is built for average adult cats. Large or very active cats can make the top levels sway, so anchor it to the wall and place it on a level floor.

How many cats does a 54-inch tree suit?

It works best for one or two cats. The multiple perches and condos give each cat a spot, but a third cat may compete for the top perch.

Does it come with a wall anchor?

Most versions include a strap or bracket for wall fixing. Check the parts list, and use your own anchor suited to your wall type if none is included.

Is the scratching post sisal or carpet?

The posts are typically wrapped in sisal rope, which cats prefer for scratching. Some sellers use thinner rope that wears faster, so inspect the wrapping on arrival.

How much floor space does it need?

Plan for a base roughly two feet square plus clearance around it. Keep it away from walkways so the tall frame is not bumped.

Is it hard to assemble?

It takes about an hour or more because of the many levels and posts. Follow the order in the instructions and tighten bolts loosely before final tightening.
