Cat Tree Materials: What You Need to Build One

A sturdy cat tree starts with a stable wood structure, durable scratching surfaces, and cat-safe finishes. Choose materials according to your cat’s size and activity level, then confirm that every platform can support the cat without bending or tipping.

Check the listed dimensions for what materials do i need to build a cat tree? against the available vehicle space before use.

Use 3/4-inch plywood for the base, platforms, and enclosed cubbies because it resists warping and holds screws securely. Cut a base at least 24 by 24 inches for a medium-height tree, increasing the footprint for taller designs or multiple cats.

Make vertical supports from kiln-dried 2-by-4 lumber, solid wood posts, or thick cardboard construction tubes with wood inserts. Assemble the frame with wood screws, bolts, washers, and metal corner brackets, then test each joint by applying firm pressure before adding upholstery.

Wrap scratching posts with 1/4- to 3/8-inch natural sisal rope, securing the ends with staples placed where paws cannot reach them. Cover lounging platforms with low-pile carpet, felt, or washable upholstery fabric, using non-toxic adhesive and closely spaced staples underneath.

Common tools include a circular saw or jigsaw, drill, staple gun, measuring tape, square, sandpaper, and utility knife. Sand every edge, avoid exposed fasteners and loose fabric loops, and use only low-VOC, pet-safe paint or sealant; for more planning ideas, see this guide to modern cat climbing trees and scratching posts.
