Domestic cats have been classified as ‘alien species’ by a Polish scientific instutite

The institute already classified different animals as “invasive alien species,” such as Japanese knotweed, raccoons, clearwing moths, and mandarin ducks, Business Insider reported.

Solarz recently has been challenged by a veterinarian in a television segment aired by TVN. Dorota Suminska touched on other reasons why biodiversity is decreasing, such as environmental pollution and urban building facades that could lead to birds’ death.

“Ask if man is on the list of non-invasive alien species,” Suminska said. Solarz, on the other hand, disagreed, revealing that cats kill about 140 million birds annually in Poland.
