under hanging from the back so the cat can't unroll the whole roll

idc unless there is a bath or shower in the room because then it gets steamy and if the paper is touching the wall it will stick.

Top and forward. Some toilet paper rolls have patterns, and the patterns show best in this position.

Not sure why, over the top just seems appropriate lol

It can be in a pile on the floor as long as I have it.

idc

Top here

Which ever way I hang it that day.

Stupid question feel free to delete it
