They're asking why animals don't have a right to life if they defend themselves.
The counter-point is that you were defending the right to self-defense, not life, and that we don't punish animals for defending themselves. Just like we don't punish people for defending themselves (except, of course, when we do). We either kill the animals for our convenience or move them for our convenience, but that's only because we deem ourselves more worthy. Our treatment of them is not thought of in terms of 'punishment'.
And then we all snicker at ourselves, because we all know that we're not supposed to kill and displace other humans for our mere convenience. But we know that ain't true. But we all know that we're mostly against the idea, as well.
