The difference is that the second he steps out of his home with them they can seize them.
As long as they remain in the home out of sight of the public, there is little the control officer can do. Unless they have a habit of breaking down doors for pets in that town, there is very little chance they will show up with a warrant to search.
And to flog the issue again, *this* is why there needs to be an organization of pet owners in Canada who can stand up for responsible owners. As long as the animals are properly contained why should they be treated any differently than other pets. We need the numbers to say that if these by-laws are in place, the cities cannot arbitrarily enforce them on a complaint by complaint basis. They either need to provide better guidelines, regulations, or dispose of them altogether.
