“Alien Invasive Species”

The Polish Academy of Sciences maintains a database of invasive species, with over 1700 entries. Earlier this week, Felis catus — the domesticated house cat — was added to the list.

Well: scientists. Sorry about that. Let me try to explain why this is accurate and helpful, not offensive or cruel.
