Here's why:
* There's no such thing as a "mouse kangaroo". Kangaroos are large marsupials native to Australia, while mice are rodents.
* Kangaroos are not domesticated pets. They are wild animals with specific needs that are difficult to meet in a typical home environment.
If you're interested in learning more about kangaroos, you can find information about their biology and conservation at websites like the Australian Zoo or WWF.
