Urine—we all produce it, and it is a natural part of our body and the way in which it works. The same goes for every animal that is out there as well, but not all urine is the same.
To illustrate what we mean, we can turn to the rather humble cat because their urine is capable of doing something that is rather different and outlandish compared to what is produced by other animals. You see, if you have the correct kind of black light, then what you will find is that the urine produced by a cat is going to actually glow in the dark. Now, that is going to be a pretty cool party trick for anybody to do, but then the cat is hardly going to be able to boast about it to all of its friends, is it?
