If you have several cats, a transparent one would prevent them from both
going through at once.

I'm not convinced.

Would video proof help convince you ?

Notice how the cat jumps back when it sees my cat through the transparant cat flap, notice how my cat waiting until the other leaves before he goes through the cat flap.

My cats go through at once from the same side.

As yuo might guess the video cature was using software which detected movement which triggered the camera this also set off an audio warning of 'intruder alert' a sound byte captured from a star trek episode.
If my cat was in the same room as the computer when this triggered he used to run down the hallway and down the back stairs to the cat flap.
Once when ST was on Red alert came up he looked around then went back to sleep as an intruder alert and red alert must have sounded differnt.

My cats aren't that clever, they're scared of a hoover.

Why can't the cats see the flap moving
and realise that another cat is coming thru the other way ?

because it could be the wind or any other reason, could be me teaching them how to use the flap which is how I got my cat to use it.
Or it could be another cat so best to stop it coming through

I didn't teach mine. They had to if they wanted fed.

Same reason as it happens with people. It doesn't move until you push it. If person/cat A pushes the flap/door while person/cat B is too close to the other side, they get a busted nose.

Otherwise this could happen: https://youtu.be/1U1jSGib-NA?t=1m49s

Unlikely with cats.

They can see through doors?

They have good hearing so don't realy as much as seeing as humans do.

Seems to be smell more than anything. I've placed a piece of cheese in front of my cat, then moved it away a few metres, and it takes ages to find it by sniffing around. It really does look silly, it should have just watched where I put it.

I can only find two models. One lasts about 2 weeks, the other lasts
about a year.

Mine would last as long as the house does.

I can't be bothered building one.

Why bother.

To make it last longer.

That would be an enormous catflap. No wonder you get burglars.

Is that how cat burglers got their name ?

No, they climb.

What revolts me is my cat eats her kittens ****.

Certain fish eat the **** of thier offspring and it actually make the adults live longer.

Cats do it to clean up, no need to do that when you're a fish and the water washes it away.

If the stuff in the **** makes them live longer, why doesn't their body keep it inside them instead of ****ting it out?

They have also found that injecting adult mice with the blood of young mice rejuvenated the older mice.

You'd think the body would learn to do this itself.

Its got nothing to do with intelligence, they evolved
like that. Just like cats did with kitten ****.

Eating a waste product is not a good idea.

It is for some animals where their digestive system doesn't remove
all that the food they eat provides it goes through a second time.

Then they should do what cows do and have more stomachs.

Nope, they clearly survive doing that fine.

I doubt they enjoy it.

What does that have to do with it, do you enjoy brushing your teeth.
Animals don;t need to do this.

I don't find it anywhere near as disgusting as eating ****.

They do only live for 15-20 years.

That's due to something else entirely.

If you know what it is, name it.

Size and DNA are part of it.
That;s why some insects live for a day and some whales can live to over 500 years old.

Pretty pointless life, one day.
