You are making an obtuse argument. You do realise pets are introduced species in many parts of the world, and actually end up being significant pests, right? Predatory pets like cats are especially destructive in most ecosystems, many small native species are vulnerable and end up being endangered, because they have not evolved a defence strategy against them. Places like Australia has a huge problem because of it.
Again, keep your cat indoors. Otherwise, you're part of the problem.
