Stop it, your compassion is reducing me to tears
Compassion for a pet would have the goalposts on greased rails. The owner couldn't have been more clear about their intent to obstruct and 4 years demonstrates that.
It was beyond this alpaca owner to have their animal destroyed and a mockery of disease control while tens of thousands of cattle (owned by emotionless farmers?) were destroyed in the UK due to bTB infection in that period.
