Tips

  • Buy wooden crates on sale to save money.
  • Use strong anchors to support the weight of books and cats.
  • Use a level to ensure the crates are evenly aligned on the wall.
  • Add a third nail for extra support to each crate.

Common Mistakes to Avoid

1. Uneven Crate Placement

Reason: Crates might not be perfectly level, leading to an unstable or wobbly cat tower.
Solution: Use shims or levelers under the crates to ensure a stable base.

2. Insufficient Sanding

Reason: Rough edges and splinters from the crates can injure your cat.
Solution: Sand all surfaces thoroughly before painting or staining.

3. Weak or Improper Attachment

Reason: Using weak screws or glue, or improper placement, can cause the structure to collapse.
Solution: Use heavy-duty screws, wood glue, and reinforce joints with corner brackets for added stability.

FAQs

What type of wood crates are best for this project?
Solid wood crates are ideal, offering durability and stability. Avoid flimsy or damaged crates. Fruit and vegetable crates are a good option, but ensure they're clean and free of any chemical residues before starting. New, untreated crates are best to avoid potential chemical exposure for your cat.
