Tips

  • Use a hand screwdriver if the angle of the bracket makes it difficult to use a drill.
  • Use longer screws (1 inch) to attach the platform to the secondary wood piece for better hold.
  • Use wood glue to hold pieces together before screwing, providing extra stability.
  • When stapling the bath mat, ensure it doesn't interfere with the platform's placement in the window.

Common Mistakes to Avoid

1. Unstable Construction

Reason: Using insufficient support or weak materials can lead to a wobbly or collapsing perch, scaring your cat and potentially causing injury.
Solution: Reinforce the structure with additional supports, thicker wood, or stronger screws and ensure proper weight distribution.

2. Inadequate Surface Area or Rough Edges

Reason: A perch that's too small or has sharp edges can be uncomfortable or even painful for your cat, making them reluctant to use it.
Solution: Use a larger piece of wood or carpet the surface and sand down any sharp edges to provide a smooth, comfortable resting space.

FAQs

What materials do I need to build a cat window perch?
The materials needed vary depending on the design, but common items include a sturdy wooden board (shelf), strong adhesive or screws, comfortable cushioning (carpet, fleece), and possibly some additional supports (like brackets or L-brackets). You may also need sandpaper and wood stain or paint if desired.
How do I ensure the perch is securely attached to the window?
Use strong adhesives designed for wood and glass, following the manufacturer's instructions carefully. For extra security, consider using suction cups in conjunction with adhesive, or screwing the brackets into the window frame if possible. Always prioritize safety and make sure the perch cannot easily be dislodged.
My cat is very heavy/active; will this perch hold up?
The sturdiness of your perch depends entirely on the materials and construction. Use thicker, high-quality wood for heavier cats. Reinforce the structure with extra screws or brackets, and test the perch's weight limit before letting your cat use it. If unsure, consult a professional for advice on building a more robust structure.
