The best pet door through a wall depends on your pet’s size, the wall’s thickness, and the opening you can safely cut. The options below include small, medium, and large Baboni doors, plus a medium PetSafe model with a plastic frame. Baboni’s listed options suit buyers who want a steel frame and telescoping tunnel; PetSafe is a better fit for buyers who prefer a frame described as rust-resistant plastic.
| Product | Best For | Key Fit Information |
|---|---|---|
| Baboni Small | Pets up to 12 lb | 4 3/4–7 1/4-inch walls |
| Baboni Medium, 3-Flap | Pets up to 40 lb | 8 1/4 x 12 1/4-inch flap |
| Baboni Large, 3-Flap | Pets up to 100 lb | 10 1/4 x 16 1/4-inch flap |
| Baboni Medium, Steel Frame | Pets up to 40 lb | 9 7/8 x 13 3/4-inch cutout |
| PetSafe Medium | Pets up to 40 lb | 4 3/4–7 1/4-inch walls |
Baboni Small Wall Pet Door
Best for: Cats and small dogs up to 12 pounds. This Baboni model has a steel frame, aluminum lock, and telescoping tunnel for walls 4 3/4 to 7 1/4 inches thick. Its flap opening measures 5 1/4 by 8 1/8 inches, and the specified wall cutout is 6 3/4 by 10 inches.
The included cutout template and instructions make it a practical choice for buyers planning a wall installation. Choose this model if its opening fits your pet’s body comfortably. Its small opening is a limitation for larger pets, so measure your pet rather than relying on weight alone.
Baboni Medium Three-Flap Door
Best for: Pets up to 40 pounds when a larger opening is needed than the small model provides. The listed flap opening is 8 1/4 by 12 1/4 inches, with a 9 7/8 by 13 3/4-inch wall cutout. Its telescoping tunnel fits walls 4 3/4 to 7 1/4 inches thick.
This version is described as having a steel frame, aluminum lock, and three-flap design. It is selected for medium pets and buyers who want the specified larger opening. Check both the cutout dimensions and wall thickness before installation; walls outside the stated range may not fit the tunnel as supplied.
Baboni Large Three-Flap Door
Best for: Larger dogs and other pets listed up to 100 pounds. The flap opening is 10 1/4 by 16 1/4 inches; the required cutout is 12 by 17 3/4 inches. Like the other Baboni models here, its telescoping tunnel is specified for walls 4 3/4 to 7 1/4 inches thick.
The large opening is the reason to choose this option over the medium Baboni models. The listing includes a cutout template and step-by-step instructions. Its larger cutout requires more wall space, so avoid choosing it without confirming that the planned location can accommodate the dimensions.
Baboni Medium Steel-Frame Door
Best for: Pets up to 40 pounds and buyers comparing a steel-frame wall door with other frame materials. This model has an 8 1/4-by-12 1/4-inch flap opening and a 9 7/8-by-13 3/4-inch cutout. The tunnel fits walls between 4 3/4 and 7 1/4 inches thick.
It includes an aluminum lock, telescoping tunnel, cutout template, and installation instructions. The dimensions match the other listed Baboni medium option, making opening size a useful comparison point. The provided details do not specify an extension for thicker walls, so verify the fit before cutting.
PetSafe Medium Wall Entry Door
Best for: Buyers seeking a wall-mounted option with a durable plastic frame described as resistant to rust. The telescoping tunnel is designed for walls 4 3/4 to 7 1/4 inches thick, and the door is listed for dogs up to 40 pounds. The product details do not provide flap or cutout dimensions, so confirm those measurements before purchase.
PetSafe notes that compatible extension kits are sold separately for walls thicker than 7 1/4 inches. Choose this model if the plastic frame suits your needs; compare its exact opening dimensions with your pet before committing to a wall cut.
Buying Guide: How to Choose a Wall Pet Door
What size opening does your pet need?
Measure your pet’s width and height at the points that must pass through the flap. Compare those measurements with the listed flap opening, not just the product’s suggested weight range. The Baboni small model has a 5 1/4-by-8 1/8-inch opening; the medium models provide 8 1/4 by 12 1/4 inches, and the large model provides 10 1/4 by 16 1/4 inches.
Will the tunnel fit your wall?
Measure the wall thickness at the planned installation site. The listed Baboni tunnels and PetSafe tunnel accommodate 4 3/4- to 7 1/4-inch walls. PetSafe specifies that extension kits for thicker walls are sold separately. The provided Baboni details do not describe an extension option, so check fit carefully if your wall is thicker.
What should you check before cutting?
Compare the product’s required cutout with the available wall area. Confirm the installation location is appropriate for a through-wall opening, and follow the supplied template and instructions where included. If you are unsure about the wall’s structure, wiring, or pipes, consult a qualified professional before cutting.
Frequently Asked Questions
Can a pet door be installed through a wall?
Yes. These products are designed for wall installation and use telescoping tunnels to span the specified wall thickness. Confirm the model’s measurements and installation requirements before making an opening.
How do I choose between the Baboni sizes?
Choose by the flap opening and your pet’s measurements. The small model is listed for pets up to 12 pounds, medium models for up to 40 pounds, and the large model for up to 100 pounds.
Do these pet doors fit every wall thickness?
No. The listed telescoping tunnels fit walls 4 3/4 to 7 1/4 inches thick. PetSafe lists extension kits separately for thicker walls; check product details for any other installation needs.
What is the difference between the Baboni and PetSafe options?
The Baboni listings specify steel frames, aluminum locks, flap openings, and cutout dimensions. PetSafe describes a durable plastic frame and gives the supported wall-thickness range, but the supplied product details do not list its flap or cutout measurements.
