How do cats urinate?

The urinary system in cats is pretty much like that in humans. When ready to urinate, the cat's brain signals him to get up and go to the litter box or area of loose dirt. Both male and female cats "squat" to urinate. The male's penis extends a little out just before he urinates. Girl kitties just 'go'. When done, girl or boy cats scratch at the litter or dirt to cover the odor of their wastes.

Interesting fact: Many cats will not have a bowel movement in the same litter box where they urinate.
