People who want to know everythingabout their pets have Friend's Mother 4 (2025)a powerful new tool.

SureFlap, based in the UK, already makes a line of products connected to pets' implanted microchips. Now it's putting out an app-enabled pet door for cats and small dogs.

It should be pretty straightforward to start tracking your pet with the ultimate pet surveillance set-up, called the Microchip Pet Door Connect. You install the pet door just like any cat or small doggie door. You plug in the "hub" which connects the door to the internet. Then your cat comes slinking in from the garden and you get a notification on your smartphone.

Beyond letting you know when your pet comes and goes, the flap is smart enough to be set to lock or unlock, which you can control from the app. As the site a bit creepily suggests, "create a curfew" for your dog. Or "protect your home," since you can now block out neighborhood cats and strays from coming in. So much power.

Like company's already-available cat flap and pet feeder, this new product uses pets' microchips. But if they don't have one implanted, RFID collar tags work, too, and are conveniently sold by the British pet tech company.

It's coming out this summer for about $200, per the Verge, just in time for tracking Fido's every single move.
