Understood. Just adding a point about tattoos. In Europe it is still quite common to tattoo cats and dogs - in fact the new law even states animals must be identified by tattoo OR microchip. It is either in the ear or just inside the top of the back leg, usually done when the animal is neutered. But of course,it is still not universal to even neuter, and many people are against it anyway, so the animal never goes near a vet. This is especially true in the countryside. The irony is that most animals wearing collars are in fact those of caring owners and are probably also tattooed or chipped.
