Everyone knows that cats kill rodents and birds. Because cats can be so destructive ti wildlife, the Polish Academy of Sciences declared cats an “invasive alien species.”
Technically cats do fit in that category because they kill so many things, but then again, human beings also fit under that category as well. Given a choice between being around people or being around cats, it’s obvious more people would rather be around cats. That proves once and for all that the most invasive alien species is always the human race.
