Let’s have a chat about a sensitive topic – even though the topic has probably ruined more relationships than chatting about sex, race, religion or politics. The topic is… the impact free-roaming domestic cats have on wild bird populations.

Invasive mammalian predators are therefore important drivers of irreversible loss of phylogenetic diversity worldwide. *
