All I need is one that locks and unlocks automatically on a timer.

My cats can go in and out all day, but I like to keep them in at night (They get into to many fights). The problem comes in when its time to let them out again at 6:30am. I work 1pm to 10pm so 6:30am is kind of in the middle of the night for me. You would think this would be a common need, but no one makes one and I don't have time/energy to custom build something.

Or, ya know... Just put a $0.50 RFID tag on kitty's collar and hook a $10 RFID reader from eBay to a solenoid.

My ex and I had a much more useful idea for anyone who owns a longhair:

The Mew-Smooth 2000TM.

It's basically a short tunnel lined with brushes that attaches to the cat door. By the time the cat enters the house, she's brushed free of excess fur and whatever else she picked up in her adventures outside.

I don't know about the States but here in the UK it's been common practice to chip pets for a number of years. That way when one turns up at a vets they wave a wand over the animal and it tells them who owns it (in theory).

I'm surprised more cat/dog flaps and such haven't been marketed that make use of these chips... most seem to revolve a round a small magnet on the animals collar which triggers a solenoid and unlocks the flap; which works a treat until either your cat looses it's collar or another one shows up with a magnet for the flap on it's house.

Unless you live in the country, where mousing is a cat's primary function on your farm, there is NO REASON to let your cat wander around the neighborhood alone.

It's rude to your neighbors, and dangerous for the cat. Letting the cat out was always meant to be a rural thing. It's not a neighborly or intelligent idea if you live in an urban or suburban area.

If your city/town has leash laws for dogs, then the same courtesies apply for cats; Don't let your pets of ANY species run around without a leash.

Of course, if for some reason you like the idea of some cat-hating neighbors hurting your cat, or some bad driver killing it, or some neighborhood dog tearing it apart, or the county animal control officers picking up your pet and eventually putting it to sleep, then by all means: Be an idiot and let your cat out in the suburbs or city.

You don't need a damn cat door if you live around other people, and if you don't live around other people, you don't need a smart cat door because you probably have smart-enough cats and dogs to deal with vermin before they try to enter your dwelling.

I locked myself out of my old house once and climbed thru the dog door to get back in. Of course any rather smallish burgler could have done the same thing but then would have to deal with a snarling angry German Shepherd.

Luckily the cat was afraid of the door because it was rigid & magnetized and thus made a very loud bang when it swung shut. He only ever dared go thru it when he lost his mind at the cheeky chipmunks tormenting him by scampering back & forth across the patio.

Here's what I want... a door that knows which cat is which and only lets certain ones in (which can be turned off).

We have one cat that likes to pee on the bed at night. But if we lock everyone out, they get awfully pissy.

100% agreed. That and fleas. Even if your cat is fixed, they'll make friends with strays.

Fleas can be dangerous to older cats... it makes them anemic.

Sounds like you need our new products: Cat House, a box lined with adhesive and baited with tuna, and Catpaper, which attaches to your vehicle hood. Once the miscreant cat is firmly stuck to either, you close the door on the cat house or roll up the catpaper and leave the animal in the trash. No muss, no puss.

Agreed, BUT to be really effective you have to do it from birth. Our cat is pushing 14 and has been indoors all her life - you could practically prop the door open with a brick and she's still not going anywhere. It's like the concept of "outside" doesn't exist in her brain.

My folks, on the other hand, have a couple of similarly elderly cats that used to roam the 'hood but got sentenced to indoor life about a decade ago. Even though they haven't been outside since the Clinton administration, those little bastards will still try to make a jailbreak if you leave the front door open too long.

Earguy: I have a friend who had a raccoon enter their home through the dog door last month. It was an interesting Facebook thread. I never heard back if it was rabid, but its behavior was.


We had a very young possum that discovered it could come in through the dog door and raid the cat food bag and whatever the dogs hadn't eaten. The really odd part is that it was on speaking terms with the dogs and cats. The dogs wouldn't bark and the cats would just sidle over and share the food bowl with it.

/Tom, there's something IN the cat food bag...
//oh, it's the possum. Get out of there...(hiss!) ok, it's the broom for you young man
///sweep sweep (hiss!) out out out the power of ocedar compels you...(waddle waddle flap!) ok, he's gone

I whacked a squirrel with a broom to get it out of my tent, and the animal fell dead at my feet.

..omigish...

Then I felt sorry for it. Kind of tried to revive it but no amount of moving it with the broom or tapping the toe of my boot on its chest would revive it.

Just one broom whack and that's all the game you got little dude? kick kick. dammit.

Ended up throwing it in the trash and shutting the hell up.

/ It was a good thing I wasn't in Yosemite National Park at the time, and that neither my boss or any park rangers were around.

Wouldn't that be extremely expensive to have all the birds, mice, and chipmunks RFID chipped too?

The article clearly states the intent was to prevent the cat from coming in with dead or dying things in its mouth.

Veterinarians are big on chipping cats here too, although I don't know how many people actually do it. It's expensive.

As a homebrew-electronics geek the only question I would have re: embedded kitty chips is how expensive the readers are. I know you can get readers for standard HID-type wiegand code chips dirt cheap, and the corresponding tags (which can be the size of a collar tag) cost pennies. Implantable tags are a lot smaller and probably on a different frequency. That probably means "less common, more expensive."

How fast does it and other similar type pet doors, such as those using RFID react? If a cat is being pursued by an enemy, such as a vicious dog, it needs to be able to hit that door wide open or it's going to be dead.

FTFY.


Depending on the transducer you use, RFID would be close enough to instantaneous to make no difference. You can get them with ranges that could encompass your entire front lawn. If kitty is within 30' of the transducer, the door is unlocked. Facial recognition, maybe notsomuch. There kitty has to present themselves to the camera.
