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.
