Honestly it's always something magical when a cat decides ah yes you are my human. It's like the dark souls version of getting a dog. And thusly cats in a way are the peak of loyalty because no one else can win a cats favor.
Technically we all have tails already. However they are made entirely of bone and aren't long enough to stick out. Really all they do is make sitting on hard surfaces uncomfortable and try to dig their way out of your ass when you do situps without a mat
I'd imagine comfort reasons also. Hell having a dick can get uncomfortable at times. Like every time I wear pants that are just to tight for a long bike trip it gets twisted around and bent into kinks. I can't imagine having what is comfort wise a second dick on the other side of my groin and pointing down. I can see that pinching itself every time you run or sit down. I really hope there aren't any nerves in them.
No it was a project back in the 1950 I think and it was this big mobile lab but because there was this belief that rounded tires preformed better in the snow the builders sanded the tread off the off-road tires they got also the engines while they had plenty of torque the fastest the artic explorer could go was 2 mph and when it finally arrived at the artic it got stuck immediately and moved faster in reverse the scientists got soo fed up with constantly digging the 70ton paper weight free that they just gave up and started using it was a small stationary base until the ice under it broke then 20 years later vw sent a bone stock Beatle that managed be the first car to drive across the artic with 0 issues
Same case here the only time I can remotely enjoy soda is when it has ice cubes added or is ramune
