Not the onion somehow.

‘Pet ferrets kept as therapy animals at the UK’s largest children’s prison have been co-opted by managers to kill rats, resulting in a bloody incident and concerns over child and animal welfare.’

'According to a union complaint seen by the Guardian, the decision resulted in a boy who looks after ferrets witnessing an “inappropriate and potentially distressing” savaging of a screaming rat.

Another complaint suggests the gored rodent was then “stomped to death” by a senior staff member in front of prison officers.

The incident once again highlights the vermin-ridden conditions in which children and adults are detained within the prison estate across England and Wales.’
