At least in north America, domestic cats are far from the top of the food chain and have many predators. Which is why they don’t live outside human civilization. Lionfish have no predators in the areas they’re invasive, which is the problem. Though it looks like both sharks and grouper can be trained by humans to eat them so once that chain is established the lionfish might start declining.
Sure, but then it dies without having children, stopping the resource consumption. It might be delayed, but it’s still a halting force. I’m also confused as to what the issue is - do they have some way of bypassing being neutered?
If your goal is to lower a population over time, neuter and release can be very effective. Neutered males will still try to mate but they will not succeed. The females they try to mate with might not mate with another male, so they miss the chance to create a new generation.

I think is a reference to feral cats.

They’re better off eating them. :)

a neutered animal still consumes resources

Just one won’t impact anything substantial.
