Questions

Should I choose a single flap or a double flap?

A double flap traps a pocket of still air between the two panels, and that air gap is what does the insulating. If you have real winters, real summers, or a door that faces prevailing wind, the second flap is the difference you will actually feel.

A single flap is easier for a hesitant, small, elderly or recovering pet to push through, and it is the better choice in a mild climate or on an interior opening where insulation is not the point. If you are torn, consider which matters more day to day: the energy bill, or how confidently your pet uses the door.

What size hole do I need to cut?

Every pet door has a hole size that is smaller than the outside of its frame, and different again from the flap opening your pet walks through. The hole size is the one you mark on the door.

You will find it in the size guide on the product page, listed beside the flap and frame dimensions, and the installation instructions include a printable template you can tape in place before cutting. Mark from the template rather than from the frame itself. The frame overlaps the opening by design, so cutting to the frame leaves a hole that is too large to seal.

Will this fit the hole left by my old pet door?

Sometimes, but it is worth checking before you order rather than after. Pet door brands do not share a standard hole size, so a large from one manufacturer is rarely the same opening as a large from another, and a new door that is slightly smaller than the old hole cannot be made to cover it.

Measure the existing hole itself, height and width of the opening in the door or wall, not the frame around it. Compare that against the hole size in the size guide on the product page, which is listed separately from the flap size. If the new hole size is larger you can usually enlarge the opening. If it is smaller, look for a door with a wider frame that will cover the gap.

Product Details

The PetSafe Microchip Cat Door utilizes advanced microchip recognition technology to grant exclusive access to your cat or very small dog while keeping unwanted animals at bay.

The 5.91" W x 5.51" H flap is suitable for cats and very small dogs, allowing your furry friends to come and go as they please.

If it is smaller, look for a door with a wider frame that will cover the gap.
Will this work in a hollow core or solid core door? Both, but they install differently. A solid core or exterior door is the straightforward case. You cut the opening and the frame clamps through the door. A hollow core interior door is mostly air with a cardboard lattice inside, so the cut exposes that void. The pet door frame still clamps front to back and holds fine, but the raw edge of the opening should be sealed or lined so the door skin cannot delaminate over time. [CONFIRM: whether we supply or recommend a specific liner for hollow core installations.]
Does the door work with my pet's microchip, or only a collar key? These are two different technologies, and most doors do one or the other. A microchip door reads the chip already implanted in your pet, so there is nothing for them to wear. A collar key door reads a small transmitter clipped to the collar, which works on a pet with no chip and lets you control access per pet. [CONFIRM: which of our electronic doors read microchips, which use a collar key, whether any read both, and whether the microchip units read all common chip standards.] Chip standard compatibility is the detail that catches people out.
Can a door mount pet door be converted to a wall mount? For some models, yes. The flap assembly is the same part, and what changes is the tunnel that spans the wall thickness, so a wall kit added to a door mount door produces a wall installation. [CONFIRM: which of our doors have a wall conversion kit available, and whether the kit is sold on its own.] This is worth asking before you buy if you are undecided about where the door is going, because starting from the door mount version and adding the tunnel later is usually cheaper than replacing the whole unit.
What happens during a power outage? It depends on the model. Pet doors offered with a battery backup option are designed to keep working temporarily through a power outage, so your pet still has access until power returns. How long that lasts depends on the model and on how much the door is used while it is running on the backup. [CONFIRM: which models offer battery backup, whether it is included or sold separately, and how the models without it behave on power loss.] This is a real objection at the point of purchase rather than idle curiosity, because a door that fails locked traps a pet outside and a door that fails open defeats the reason for buying an electronic door.
Can I buy a replacement collar key? Yes, replacement collar keys are sold separately. Additional keys are also how you add another pet to an electronic door, since each pet carries its own. Warranty coverage on a collar key is set by the manufacturer of the door, and it is often different from the warranty on the door itself, so contact them directly for the terms that apply to your model. In practice collar keys behave like consumables: they are battery powered, they get lost, and they get chewed, so it is worth knowing the replacement cost before you buy.
