How to Choose an Interior Cat Door

Matching the right door to your home and pet is key. Some options require cutting, while others are tool-free and removable.

Door Style and Material

Flap doors offer privacy and draft protection, while open designs are silent and easy for timid cats.

Locking Mechanisms

Locking options help control which pets can pass and when. Four-way locks add flexibility for multi-pet homes.

Installation Requirements

DIY installs are common, but tool-free props are best for renters or temporary setups.

Size and Accessibility

A door that’s too small may discourage use, while too large could allow unwanted access.

Safety and Home Environment

Think about who needs access and whether you want to block drafts, noise, or other pets.

FAQ For Cat Door Interior Options

1. What size cat door do I need for my cat?

Measure your cat’s height and width at the shoulders, then choose a door with an opening slightly larger to ensure comfortable passage.

2. Can interior cat doors be installed in hollow core doors?

Many interior cat doors are designed for hollow core doors, but always check the installation instructions and use the recommended hardware for a secure fit.

3. How do I keep dogs or children from using the cat door?

Select a door with adjustable width, locking mechanisms, or a design that only allows cats to pass while blocking larger pets or toddlers.

4. Is it possible to remove a cat door later without damage?

Tool-free props and latch holders can be removed without damage. Flap or cut-in doors may leave a hole that requires patching if removed.

5. Do I need special tools to install an interior cat door?

Most flap-style doors require basic tools like a drill and saw, while latch props often need no tools or just a screwdriver for setup.
