A quality pet door gives your cat independence and keeps you from playing “doorman.” But the right cat door isn’t just a hole in the wall—it’s a secure, well-designed passage that keeps out weather, strays, and even neighborhood raccoons. Whether you need an interior or exterior solution, manual or microchip-activated, here’s how to pick the best pet door for your cat, plus today’s top-rated options.

Buyer’s Guide
What should you look for in a cat door? Here’s what matters most:
- Size: Cats like a snug but not tight fit. Standard cat doors are about 5.5” to 7” wide and 6” to 8” high. Measure your cat (height and width at the shoulders) and add an inch for comfort.
- Security: For outdoor access, microchip or RFID-activated doors keep out strays, raccoons, and neighborhood pets. Locking manual doors are a good, low-tech option.
- Insulation: If the door will go outside, choose a model with weather seals or double flaps to keep drafts, rain, and snow outside.
- Installation Type: Cat doors can be installed in doors, walls, or windows. Check your surface and follow manufacturer guidelines for the right fit.
- Ease of Use: Make sure the flap swings easily and quietly. Magnetized flaps can be a plus, but too strong a magnet can deter timid cats.
- Looks and Finish: White, brown, and gray frames are common—pick a color that matches your decor or door style.

FAQ Section
How do I train my cat to use a pet door?
Start by taping the flap open and coaxing your cat through with treats or toys. Gradually lower the flap until your cat pushes through it on their own. Most cats learn within a day or two!
Are microchip cat doors worth it?
Yes, if you need security. Microchip doors stop strays, wildlife, or neighboring pets from coming inside. They’re especially valuable in busy neighborhoods or for multi-cat homes.
Can I install a cat door in a wall or window?
Many doors have wall kits or are compatible with thin glass panels. Always check the product specs before cutting, and consider professional installation for glass or thick walls.
How do I keep the door weatherproof?
Choose a door with a strong seal or double flap for outdoor use. For extra protection, look for models with brush seals or magnetic closures that keep out drafts and rain.
Is there a pet door that my dog can’t use, but my cat can?
Yes! Several “cat only” doors use a smaller opening, microchip, or magnetic system. Some interior doors are designed for cats but are too small or high for most dogs to use.
