Question:
Can you please advise whether kangaroos (any species) urinate?

Replies:
I think you are confused with kangaroo rats, which do not urinate in order to conserve as much water as possible. They have incredibly long Loops of Henle in their kidneys which allow them to reabsorb any water that would be given up to the environment. They survive on metabolic water alone (ie the water that is formed in cellular respiration).

Dr. Van Hoeck may have made the correct evaluation of your request. However, the marsupial Kangeroo does urninate like most mammals.
