Our verdict

A steel-framed wall pet door with double magnetic flaps and lockable panels for cats and small pets in all weather. It needs a wall cut, so it suits homeowners more than renters.

Overview

Cat owners tired of opening the door all day get a wall-mounted pet door with a rust-proof steel frame and a telescoping tunnel that spans the wall. Double magnetic flaps seal out wind and rain, and sliding panels set it to open, locked or partly open.

Weather sealing is the reason to buy, from two magnetic flaps in series plus sliding lock panels. The steel frame stands up to chewing and clawing. The limit is installation, since cutting through a wall is permanent and the opening only suits smaller pets.

Who it's for

Homeowners whose cats roam a yard or porch get independent access with a strong seal against weather. Larger dogs and households that cannot cut a wall should look at a door-panel or window insert.

Pros and cons

Pros
  • Steel frame resists chewing and clawing
  • Two magnetic flaps for weather sealing
  • Three lock modes with sliding panels
  • Telescoping tunnel spans wall thickness
Cons
  • Requires cutting a wall opening
  • Opening too small for larger dogs
  • Fasteners and tools not listed
  • Partial open mode lets in air

Performance notes

Sealing comes from the two magnetic flaps, which close one after the other so drafts must pass both. The telescoping tunnel lines the cut so wall material stays hidden and pets do not catch on edges. Lock panels slide in to set access, so control depends on remembering to change the mode.
