Reminder that a cat named Tibbles once rendered an entire species of New Zealand wren extinct: https://en.wikipedia.org/wiki/Lyall%27s_wren

The article itself seems to disprove this? It wasn't all caused by a single cat.

All Tibbles had to do was eat the last one (or the second to last).

Tibbles was the first cat brought to the island, and she had kittens, hence the feral cats.

Tibbles didn't kill them all, but bringing Tibbles doomed the species.
