First of all they said free-roaming cats, not feral cats.

You can't ban feral cats any more than you can ban rats or trees.

And you're excluding the middle too. It's not as though any policy which isn't perfectly and totally enforced is completely ineffectual. And it's also not the case that policies that don't solve a problem completely should be discarded as pointless.

In the end, to have any solution at all, you need something that a) works to some extent and b) can be agreed on by enough people to actually end up being executed.

Far too often the discussion gets completely bogged down in a where a has to be accomplished utterly and completely or we shouldn't bother at all. But the only thing that's pointless is having the discussion that way, because the world just doesn't work like that.
