It seems to me, and this is a devil's advocate observation, that if I was to befriend a feral cat colony, start meeting their needs by feeding them, trapping them and spaying them, I could legally define my wild cat colony as stray. And therefore, they would be protected.
The kind people who care for the Paihia cat colony assert they are spayed and do not breed.
All of them? Is there an accurate record of the total population?
In terms of the definition of these cats, here is another factor to consider.
The Advocate has asked to photograph the cats, with someone holding one of them.
I can assure you that the only way we will be photographing one of these cats is with a long range lens from a camouflaged mai mai. You cannot approach them, and cuddle them. They are wild - something that is not defined under law.
It seems in this situation, the law is an ass - the latter being something I suspect these cats are laughing off as we speak.
