Sizing for Your Pet

Door height = pet shoulder height + 1". Door width = pet shoulder width + 1".

Small (cats, small dogs): 6-8" opening.

Medium (most dogs): 10-12" opening.

Large (Labs, Goldens): 13-15" opening.

Smart Microchip Doors

Microchip-activated doors only open for your pet's chip — keeps neighborhood cats and raccoons out. Premium security but $400-600 vs $50-150 for basic doors. Best for outdoor cats.

Frequently Asked Questions

Wall or door mount?

Wall mount looks best, doesn't compromise the door. Door mount is cheaper but limits door replacement.

Slider insert any good?

Yes — perfect for renters or test-drive. Drops in/out without modification.

Microchip door worth premium?

Yes if you have outdoor cats — keeps strays out. Otherwise standard pet door is fine.

How much for pro install?

Wall-mount: $179-499 + door cost. Slider insert: $0 (DIY drop-in).

Can pets learn to use the door?

Most do within 1-3 days. Smaller dogs and cats may need a few days of treats-on-the-other-side training.
