Anyone who declaws a cat should have the last joint of every finger
removed with a machete. Then, their home should be filled with feral
cats to scratch every piece of furniture to shreds.

Toes too. Don't forget the toes.

I had a cat once whose canine teeth had been removed because of a jaw
infection. It was a lot of fun to play-fight with him.

So my cat sneaks out when people come in/out the door.
She's an indoor cat, but very sneaky. I don't mind too
much except when its like -5 out and the wife sends me
out at midnight to find the stupid cat.

How can I detect when a cat is in the doorway? I was
thinking an optical sensor about 5" from the floor in
the doorway but I don't want it to detect everything,
just this one cat. Is there some simple detector I can
make for a simple RFID tag (attached to the cats collar)?
I don't know anything about RFID tags. Where does one
even get them in small quanities (other than steal an
item of clothing with one of them embedded in it)?

I have read a little online about resonant circuits
and using a wire loop as part of a detector circuit
(I guess thats really a simple RFID tag), but I didn't
find enough info to help me build anything. For the cat,
I need something thats not powered and small enough to
attach to a cat collar.

Any helpfull thoughts?

Thanks.

In looking through today's selection of fine junk mail, I came
across this gadget for $200 that is actually pretty cool and
comes with 10 RFID tags ..

OK, OK, so I went a few pages farther in the same flyer and
found this gadget for $59 that only responds to your cat ...

( I am always snooping in catalogs like that for ideas for
cute little gadgets to make for my house etc.)

Sure. You still had your canines!

Oh? But they do. One of my most hilarious observations... my black
Burmese jumped over the back fence and, just as quickly, jumped
back... seems there was a Doberman standing on the other side ;-)

80cm is less than three feet. What did you do to this

cat? Cut off its feet when you declawed it?

Much simpler. Age took it toll, and overfeeding too.
This 15 year old male norwegian woodcat basically has
four locations. Before the feeding pot. Before the
door leading to the garden. At the other side of this
door. And on a reserved chair.
This chair with 50cm height is about the height it goes
up. Which is not much considering it is that long already.

you haven't figured that out yet!, it's a male! they like pissing

on everything around that has some meaning to you. its a way of
saying, " I am the king of this house"

I have three Dachshunds and a Burmese cat... a BIG cat, I've posted
pictures in the past. The get into big running contests throughout
the house, with some jousting. The cat always wins ;-)

Two cats here. An orange tabby that weighs in at 22lbs and a
black/white stray that *only* weighs 13lbs. The black cat can open a
serious can of whoopass when he wants. ;-)

They're both indoor cats, but I let the black one out to "greet" the
neighbors cat that was prancing around the back yard. To this day, I
really feel bad about doing that to the neighbors cat. It just stood
there with a blank look on it's face as my cat literally ripped across
the yard towards him. Like he was thinking that he was about to make a
new friend. Man, I really thought my neighbor was about to be pissed
over his freshly slaughtered cat when my cat pounced on him.
Fortunately (for the neighbors cat) I was able to get there in time to
grab my cat by the scruff of the neck and pry him off long enough for
the neighbors freshly indoctrinated cat to jump the fence (about .3 secs
as near as I can tell). ;-D I frantically ran to the house with my now
viciously wild and howling cat at my scratched and bloody arm's length.
By the scruff of the neck, I threw him into the house. You couldn't go
anywhere near him for about 30 minutes unless you wanted to stand in for
the neighbors cat. That's primarily why he's not allowed outside.

Something about the smell of the great outdoors turns him into a
howling, wild animal. He puffs all up and snorts something like a wild
hog. Kind of an incredible hulk like transformation.

This latest cat in indoors-only... we have big-ass hawks; and an owl
that I'm even concerned might try to fly off with one of the dogs...

Since I'm not the king either, it is not the cat.
I realized it is somewhat of a firmware issue, a genetic
program. That still doesn't make it acceptable though.
It is not allowed to be unattended in the living room,
thus in winter it is put into the bath room also for
the night. In summer time it can choose to sleep outside.

Actually it may not. An in door cat can become lost easily. The the
outdoors map has not been downloaded into the route finding software.

....And this is bad, how?


PS:

Cats Move On: When our cat disappeared, we found it six months later at a
farm; obviously in a better home judging from how fat the thing had become
and the utter disdain the thing showed as a recognision of it's former
riff-raff owners. We left it there.

I.M.O:

Cats *need* to kick rivals off their turf in order to hunt, torture and kill
small animals to preserve their mental balance; The screwiest cats I have
known people to lumber themselves with, are "indoor cats". I.O.W. Your cat
needs air.

No empty batteries and nothing else interferes in this
aim. Checking whether this gate is open doesn't require
equipment either.
