I live in a small city in the US, where it’s grass everywhere. There’s lots of rabbits, but why aren’t there more? They eat grass, and there’s clearly more grass than they can eat at their current population size. There’s no significant predators to speak of, I don’t think. They breed legendarily quickly, there’s even an expression about it. So if food isn’t a constraint, predators aren’t a constraint, what is the constraint? I would think they should just increase population until we don’t have to cut our grass anymore.

I regularly see rabbits on urban greenway trails in Portland. I can often see rabbits foraging in my parents back yard and occasionally they will get pieces of rabbits left on their driveway.
Cannon Beach (also in Oregon) has an [exploding population of feral rabbits](https://www.opb.org/news/article/cannon-beach-has-a-rabbit-problem/). They’re kind of a tourist attraction.
