My hometown is spending more than 1m US$ for a simple one lane roundabout, assuming an up-to-code terminal and runway would not be at the same price levels.
Books and texts were rare and expensive until the invention of the printing press, the teacher/preacher used to have one copy and was reading it out loud for the whole class/congregation. Many could not read, so they had to have someone reading the sacred texts for them. Having one book for the whole class - many learned to read upside-down or side-ways while gathering around the teacher.
They could poop inside the box but digging it out by mistake when trying to cover it.
If you have more than one cat, one might be stressed by the other(s), especially if new.
Cat might be too old or too small to climb into the box, or not feeling well.
Some cats are assholes and doing it on purpose to show you they are not happy (is the box clean?).
