The three Rodent Metabolic Cages are for rodents weighing less than 300 grams. All are identical in size but are supplied with different components for different sized rodents.
These Metabolic Cages include four fluid collection tubes with funnels (two water spillage tubes and two urine collection tubes), two feces collection tubes, two urine rings and a feeder chamber and drawer sized for the animal specified. The Cage for Mice also has mouse-size support grid and urine collection tubes. The Diuresis Cage for Mice is identical in size to the Metabolic Cages but has a smaller separating cone and collection funnel to minimize evaporation. It is used to collect by-products from a single mouse.
