I am confused by "Initially, all cats in shelters will be sterilised" ... why aren't they doing that already?? Also confused by "It won't be easy. They'll never be able to sterilise all the cats" ... obviously not - no legislation is 100% effective! And what about "If you buy a very expensive cat for €600 and want to have kittens, you can't sterilise them all," uuummmm, can't you?
