That's the problem, nobody will accept responsibility for the animals, not Mostyn's nor the council, below was a reply received by someone on FB, which if taken at face value, whatever land they are on, they are responsible, although looking for an answer to the problem, this could backfire on a member of the general public.
"Spoken to 2 people in council and the Park Rangers were also involved. I was told that, as they are feral, there is nothing at all they can do AND WHILST THEY ARE IN MY GARDEN I AM RESPONSIBLE FOR THEIR WELL BEING!! Even though they all accepted that, when the goats jump over my gate to get out, the goats could land on a person, toddler or in front of a moving vehicle causing serious personal injury, there is still nothing they can do!"
PS They have a new member, below ! and their own FB page ! Llandudno goats
