Source: How Much Do Cats Actually Kill?
I did the math to figure out how many furry forest critters my one hunter cat actually killed. Here are the numbers:
She’s 10 years old, but she’s spent the last year as an inside only cat, so let’s mark her down as 9 years old. As an indoor-outdoor cat, she averaged around 4 kills a week. According to this study, she was probably killing 16 per week. At least.
There are 52 weeks in a year, so my cat was killing around 832 moles, voles, rats, and mice per year.
At 9 years old, her kill count was most likely around 7,488.
I’m lucky that she only went after rodents and not endangered animals. With a kill rate like that, this one cat could’ve wiped out an entire species.
And that’s just one cat.
