I Cut a Hole in My Door and Now Only My Cat Can Use It — PetSafe Electronic Smart Door Review

There’s a specific kind of panic that hits you at 2 AM when you hear something rustling in your kitchen, and you realize it’s not your cat. It’s the neighbor’s cat. Or a raccoon. Or — and I’ve seen this happen — a skunk that somehow figured out how the flap works. Congratulations, you now have a wildlife problem and a smell problem.

That’s the dirty little secret of traditional pet doors: they’re equal opportunity. Anything that can push a flap gets VIP access to your home. Which is fine if you live in a hermetically sealed bubble, but for the rest of us sharing a neighborhood with ambitious raccoons, it’s a real issue.

Enter the PetSafe Electronic Smart Door. The concept is almost stupidly simple: your cat or small dog wears a little sensor key on their collar, and the door only unlocks when that specific key is nearby. No key? Door stays locked. Raccoons stay outside where they belong.

I honestly think this is one of those products that solves a problem you didn’t fully realize you had. Sure, you know random animals can walk through a pet flap. But until you’re shooing a possum out of your laundry room at 3 AM, you kind of just… live with it. This door puts an end to that nonsense.

The install is what you’d expect — you’re cutting a hole in a door, so it’s not a lazy Sunday project, but it’s also not rocket science. PetSafe includes a template, and if you’ve ever used a jigsaw, you’ll be fine. The door runs on batteries (4 AA), and the collar key has its own little battery that lasts months. There’s a manual lock too, so you can lock it in either direction when you want to keep your pet in or out.

Pros:

• Only your pet gets in — no more wildlife surprises
• Collar sensor is small and lightweight; my friend’s cat stopped noticing it after day one
• Manual lock gives you full control when needed
• Battery-powered, so no wiring needed
• PetSafe is a brand that’s been around forever — solid customer support

Cons:

• You have to cut a hole in your door. That’s permanent. Measure twice, panic once.
• The sensor range can be finicky — some pets need to get pretty close before it clicks open
• Only rated for pets 4–15 lb, so this is strictly for cats and tiny dogs. Your Golden Retriever isn’t fitting through here (and honestly shouldn’t be shown on this blog — check out our review of the lifting harness for bigger dogs instead)
• Replacement collar keys aren’t free, and your pet will lose one eventually

Who This Is For:

Cat owners and small dog people who live somewhere with wildlife. If you’re in an apartment building with no exterior doors, this is obviously pointless for you. But if your cat has yard access through a pet flap — or you’re tired of being your dog’s personal doorman — this thing earns its spot on your door pretty fast. It’s also clutch for people who want to keep their indoor cat from bolting while still letting the dog come and go.

Who It’s NOT For:

Anyone with medium-to-large dogs. Anyone who can’t commit to cutting a hole in an actual door. And anyone whose cat is a master escape artist who figured out how to ditch collars — this system only works if the key stays on.

Look, at around $104, it’s not the cheapest pet door on the market. But it’s also not just a hole in your door. It’s a bouncer for your house. And honestly? After the first time you watch a raccoon walk up to it and get denied, you’ll feel like it paid for itself. Grab yours on Amazon — your future self (the one not chasing possums at 3 AM) will thank you.
