Trick to make cat drink more water

Yes, but they often don't drink enough water and get that dark yellow
pee.

How do I know what color her pee is? Easy. I use a small aluminum
try (think deep dish from Papa Murphy's) with cat litter inside it, the
tray goes into the smaller litter box. Most of the time, her pee is like a
powerful stream which hits the sides of the litter box, avoiding the actual
litter (and saves money too).

At the risk of demonstrating my ignorance, why do you need to make cats
drink water? Don't they do it on their own ?
