I disagree with just one thing, I don't consider foxes to be vermin either. It's an animal that has as much right to be on the planet as we do. There are however, plenty of humans that I would describe as vermin. But spot on with the cats.
I agree. We sometimes receive a visit from a fox in our garden. It does no harm and is quite an attractive specimen.
Human vermin? Yes. There are plenty of those. The difference is that animals act on instinct whereas some humans are just evil.
