Steve, the TCS would do it providing you can get enough light on the cats
so that the TCS can detect it. The problem is that each cat will have a
different color for different parts of the body, and the TCS would have to be
"taught" the color of each cat. I have a TCS 230 if you would like to have it for
a few days to experiment with. The thing to remember is that you want to
detect the cats GOING IN, so you would only have to teach the TCS one side of
each cat, and you don't have to detect the cat that has permission to enter. I
assume spray painting the cats is not an acceptable alternative [noparse]:)[/noparse])

No - the TCS uses a very bright white LED at about 1 inch to detect M&Ms.
Assuming the cat breaks an IR beam to trigger the TCS, perhaps it could also
turn on a bright light. How about one of those inexpensive video monitors
from Radio Shack. I have one looking down the sidewalk to my front door and it
works great. They can be set to sound an alarm from their built-in motion
detector.

her to eat special food. I feed her in a different location than
the other 2 cats, but the problem is that one of the other cats
insists on sneaking in and stealing her food.
So... I need a detector that can "watch" across a doorway
and watch for cats entering a room and sound an alarm
if either of the WRONG cats enter. I would rather not resort
to using a "special" (magnetic) collar on the cats, and would
prefer to find a way to distinguish between cats visually if
possible...
One cat is black, one is mottled grey, and one is mostly
white.cream colored with dark siamese "points".
I'm wondering if the TCS230 color sensor kit has enough
range (30+ inches) and sensitivity to detect and "sort"
cats by color as they cross through a doorway..?
Anyone have any thoughts on how to detect a specific cat?
Thanks much!

modules. I just used an EZPASS on the NJ turnpike at 55 MPH. I don't think
cats are any faster than that...
Also, you can get bug detectors for spy stuff that are supposed to detect a
PN junction in a room. I'm guessing it floods the room with RF energy and
listens for a detected signal.
Also, the cats might have totally different visual signatures under IR or UV
bandwidths. But I don't know of any studies to that effect.
An interesting thing to think about as I have three cats as well (one that's
allergic to fish, and must be fed separately).

The RFID tags would probably be just the thing, except that I'd
rather not have to "attach" anything to the cats. I used to try and
keep collars on the cats, but had poor luck. The collars always
disappear in a few days. Sometimes I find then in the brush
outside, sometimes I never find them at all...
Anything that uses a special "ID collar" is not going to work well.
It would be far preferable to try and distinguish between cats
based on some physical feature they already have. Color seems
like it might be easiest to detect. (at least with these particular cats)
The "skull shape" thing that Harry suggested seems interesting,
but it also sounds like it might be more difficult and expensive to
implement than a color sensor...
Cost is definitely an issue. Assuming I already have a stamp to
use, I'd like to be able to put something functional together for
under $100 if possible.

Hmmm... thanks Sid, I may take you up on the loaner TCS offer!
I figured a small light that shines across the doorway to illuminate the cats
as they walk through.... I don't know how much light the TCS needs to
see by. Do you think a small flashlight would be enough to illuminate
a cat at 30" in the dark enough for the TCS to "see" it?
And no, painting the cats is not an option! (-:

they can identify a lost cat or dog, collar or not. I'm not sure I want to
be the one to hold down the cat to "inject" it though..... My little calico
bit all the way through my thumb when I tried to give her a flea bath once.

to detect the tags remotely, that does not require a specialized reader. All
you want is information that the cat is there, not the data from the pet
tag. I cannot keep a halter on my horse either, so can sympathize with you.
Good luck!

If your cat is verbal, you might consider meow

Kinda like Pavlov in reverse.. the cat would meow to

in place, the cats can earn rewards points ...
Anyway, two more attributes you could possibly use: the weight of the
cats and their size (length or height). If the cats could stand on a
weigh scale, or something spring loaded with a switch ... if one cat
weighs 5lb and the others 8 and 10 it would offer some lattitude in
measurement (wouldn't need to be precise).
Size (length) would maybe easier with the image sensor perhaps.
Determining length or height as opposed to color? I don't really know
for a fact that it would be easier - just a guess.

My dog has a rifd tag becuase he likes to escape. Anyway, the chip only sends out a serial #, and the reader gets the # and looks it up on a database Which has the pets info. I'm not sure, but doesn't the chip send out a very weak signal and the receiver amps it up? It sounds Like the RIFD Route would be too expensive, but a sweet setup [noparse]:)[/noparse]

I entertained something like this as I also have a
cat.
If your cat is verbal, you might consider meow
recognition...
Kinda like Pavlov in reverse.. the cat would meow to
get food.
Just a thought,

food in a box with an open side. Build a sensitive scale consisting of
a flat plate supported by one or more load cells, and put it in front of
the open-sided box. When one of the "wrong cats" steps on the scale,
activate a solenoid which closes a door on the food box. Open the door
when the "wrong cat" steps off the scale. Leave the door open for only
the "right cat."
This also excludes the approach of more than one cat simultaneously.

RFID tags sounds the most straightforward. And with an update system in
place, the cats can earn rewards points ...
Anyway, two more attributes you could possibly use: the weight of the
cats and their size (length or height). If the cats could stand on a
weigh scale, or something spring loaded with a switch ... if one cat
weighs 5lb and the others 8 and 10 it would offer some lattitude in
measurement (wouldn't need to be precise).
Size (length) would maybe easier with the image sensor perhaps.
Determining length or height as opposed to color? I don't really know
for a fact that it would be easier - just a guess.

mentioned.
We have two cats, both of whom have collars with small bells in an
attempt to cut down on the local bird casulaties.
You might want to consider putting bells of different tones on your cats
and detect them audibly. Now range and direction should also be less of
an issue.

Which brings up a question my wife asked...Wouldn't the light scare
the cat when it suddenly came on? IN fact, my wife had another
question that I wanted to ask...If the cat that is supposed to be in
there is, and another tries to enter, will the alarm still go off?
Perhaps scaring away the cat that should be there? Inquiring minds
want to know!

3 cats don't weigh exactly the same, (whats the odds of that) it could be
done using an pressure sensor under the doormat. or what about detecting
the height of the cat. Ummm that could be more tricky.
I had a different cat problem last year. my neighbours cats kept insisting
they wanted inside my garage. Now I didn't mind them visiting but don't
want having sleep overs. So I noticed about how tall the cats were, set up
a photo detector to sense when a cat comes in. Then a loud beeper would
sound scaring the cat back out. Its really super simple but effective.
