Once they get over the rumbling and squashing effects of takeoff, I think they'll love outer space!
Our planned rotational gee load will be a third of a gravity. They will feel like kittens again!
I would not be surprised to see a healthy cat be able to leap twenty feet straight up, (in Martian gravity!)
We will all feel better. The most extreme maneuvering thrust will only accelerate us to two/thirds of a gee. We will hardly notice such things.
It's difficult to say where the best view will be. Even finding a comfortable spot out on the meadow should be spectacular, as the sky overhead turns black, and Earth rotates into view every few minutes!
Oh Kewl!
Me Too???
