Here is a video of a fish on a parabolic flight:

I found a YouTube short describing some results of the Skylab 3 experiment:

But if there are fish or octopuses up there, too, the cat will have something to watch or to do.

I knew a guy that trained his cat for space. You could tie this cat into a knot and he would stay that way until you lifted him up. His training method? He put the cat in a toilet bowl, closed the lid and flushed it repeatedly for about an hour.

Not that I recommend it, but this was the least neurotic cat I’ve ever met in my life.

I guess all the air is filtered anyway but those filters are going to get clogged with hair every single day. Do we send hairless cats and dogs or make them wear clothes?

You read my mind, Andrew_W, and beat me to post it!

I have always felt that we should send a cat to the Space Station.

This would be the one time I would favor declawing … at least till we know the result.

One of the earlier SF authors (Clarke?) once recounted an experiment conducted to determine how cats would orientate themselves in zero G, the original plan was to send a cat up in something like the vomit comet, but that was decided to be too expensive way back then, so the plan was changed to sending the cat up in a fighter jet inside the cockpit with the pilot.
As recounted, the video showed the cat clinging to the pilot as the aircraft climbed to altitude, then when the pilot throttled back to achieve zero G he pulled the cat off him, and released it in free air inside the cockpit, magically the cat was able to seemingly teleport itself across the cockpit and re-attach itself to the pilot, the pilot tried it again and the same thing happened, on the third attempt that cat WAS NOT GOING TO LET GO, so little was discovered other than than in unusual situations cats instinctively cling to humans as a point of stability.

A cat looks at its Human and thinks, he feeds me, gives me shelter, and cares for me, I must be a God.

>They will need their claws to hunt for escaped lab-rodents.

I’m not sure however, how we attach those Velcro-booties to their paws, while maintaining claw-extension, so they can perch in a stable fashion. (But that’s for the engineering-department.)

ok, I can’t resist–

not to mention that classic Nasa video from the… what is it, the Vomit-Rocket (?)

In my 50+ years of life there has always been a cat in the mix. My parents had them and when I was growing up and when I went out on my own, one of the first things I did was acquire a cat.

I can tell just by the inflection of a meow what it wants from me that is when it wants to interact with me in the first place! The old saying goes that a human does not own a cat but rather is eventually trained to serve it and in my experience that is indeed true.
