ELI5: how did species like felines not overrun the Earth before we learned how to neuter?

I have personally known several housecats who had more than 25 babies in 12 months. I do not understand how that is sustainable.

Because they have a stupidly low survival rate and a ton of natural predators. It is a strangely common misconception that wild animals somehow survive as well as domestic animals. Of those 25 the expected survival rate is like 2-4.
