I found this without much effort, has this been debunked?
Theres nothing to debunk because its not an actual study. Its an aggregate of numerous reports, some going back a century, and some that have been debunked. They use wide ranges of estimates of how many outdoor cats there are (which range from 20 million to 120 million) and how many small mammals and birds they think they kill in a year. Then they CHOSE a number range they THINK is conservative and make calculations on that.
There is not a single study that accurately tracks how many birds are killed by cats in a year. There isnt even an accurate census on outdoor cat populations
