Colorpoint: This is the cat on the left in the photo above. Colored mask, ears, feet, tail, nose and paw pads. Similar in color pattern to a Himalayan. Here is a photo of a 9 week old seal colorpoint, noting the color difference between the kitten and the adolescent on the left above:
From there, urine travels out of the kidneys through the ureters to be stored in the bladder (a muscular sac in the lower abdomen). The bladder expands as it fills and can hold about 2 cups (half a liter) of urine at any given time (the average adult produces about 6 cups, or 1Â½ liters, of pee per day).
The kidneys make urine when they filter the blood. Urine flows from the kidneys through a pair of thin tubes, the ureters, to the bladder, where it is stored until a person urinates. During urination, muscles in the wall of the bladder contract, forcing urine out of the bladder and into a tube called the urethra. At the same time, the sphincter muscles that surround the urethra relax. Nerves carry messages from the bladder to the brain, telling the brain that the bladder is full.
